Convert a density of 1,235 kg/m3 to grams per cubic centimeter

Answers

Answer 1

Answer:

Density, [tex]d=1.235\ g/cm^3[/tex]

Explanation:

It is given that, the density is 1,235 kg/m³.

We need to convert the density to g/cm³.

We know that,

1 kg = 1000 g

1 m = 100 cm

[tex]1235\ kg/m^3=1235\ \dfrac{kg}{m^3} \\\\=1235\times \dfrac{1000\ g}{(100\ cm)^3}\\\\=1.235\ g/cm^3[/tex]

So, the density is [tex]1.235\ g/cm^3[/tex].

Which of the following statements is a true statement concerning a reaction that has reached a state of equilibrium?
a. A system has reached equilibrium when there are equal amounts of products and reactants present in the system.
b. A system has reached equilibrium when the rate constant for the forward reaction equals the rate constant of the reverse reaction.
c. A system has reached equilibrium when the reaction has stopped and no more products are formed.
d. A system has reached equilibrium when the concentrations of reactants and products remain constant.

Answers

Answer: A system has reached equilibrium when the concentrations of reactants and products remain constant.

Explanation:

The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.

The equilibrium is dynamic in nature and the reactions are continuous in nature. Rate of forward reaction is equal to the rate of backward reaction.

Equilibrium state is the state when reactants and products are present but the concentrations does not change with time, that is the concentration remains constant.

What is the mass of a 67 dL sample of a salt solution?

Answers

Answer:

6733.5 g of NaCl

Explanation:

We can assume that the salt solution is a saline solution which contains NaCl in water at 0.90%, whose density is 1.005 g/ml.

So we need to apply the density concept to solve the question.

Density = mass / volume

We convert dL to mL → 67 dL . 100mL / 1 dL = 6700 mL

Density = mass / volume

Volume . Density = mass

6700 mL . 1.005 g = 6733.5 g of NaCl

How many mL are equal to .0024 L?

Answers

Answer:

1

Explanation:

1000ml=1l

? =0.0024l

0.0024/1000×1

0.0000024ml

Volume has been the amount of space covered and occupied by the substance. The volume of the substance has 0.0024 liters is equivalent to 2.4 milliliters.

What is volume?

Volume has been defined as the three-dimensional space that has been occupied by the substance in space. It has been measured in derived units of length like cubic meter (m³), cubic centimeter (cm³), liter (l), and milliliter (ml).

The units of the volume can be converted into various derived units by multiplication and division of the units. The small units are derived from larger ones by multiplying and larger units are converted into smaller ones by division.

Given,

Volume = 0.0024 L

Converting units as:

1 liter = 1000 mL

0.0024 L = 2.4 mL

Therefore, the volume is 2.4 milliliters.

A certain block is floating in water with 77% of itself submerged. It has a length of 4.3 cm, a width of 5.9 cm, and a height of
2.75 cm. What is its mass, in kilograms?
a. 1.86 kg
b. 2.77 kg
c. 0.0086 kg
d. 5.98 kg
e. 3.62 kg
f. 0.0537 kg

Answers

Answer:

f. 0.0537 kg

Explanation:

To solve this, we use the formula for force of buoyancy (Fb) = Vs × D × g

Where; Fb= Force of buoyancy

Vs= Volume of submerged

block

D= Density of water that block

submerges in

g= acceleration due to gravity

In this question, volume of block can be calculated using L×B×H

= 4.3cm × 5.9cm × 2.75cm = 69.7675cm^3

If 77% of the block is submerged in water, then 77/100 × 69.7675cm^3

= 53.72cm^3 is the Volume of submerged block

Density of water is known as 1000kg/m^3 while the gravitational force is 10m/s^2

We need to convert the Vs (volume of submerged block) to m^3 by dividing by 1,000,000

Hence, Vs = 53.72/1000000

Vs= 0.00005372m^3

Using the formula; (Fb) = Vs × D × g

Fb = 0.00005372m^3 × 1000kg/m^3 × 10m/s^2

Fb = 0.5372kg/m/s^2

Therefore, the force of buoyancy of the object on water is 0.5372kg/m/s^2

Recall that; Mass (m) = Volume (V) × Density (D)

Force of buoyancy (Fb) = Vs×D = mass (m) × acceleration due to gravity (g)

i.e. mass = Fb/g

= Mass of the block = 0.5372/10

Mass = 0.05372kg

Therefore, the mass of the block in kg is 0.05372kg

Which of these relationships is true of an uncharged atom?
A) The atomic mass is equal to the atomic number.
B) The number of electrons is equal to the number of neutrons.
C) The number of protons is equal to the number of electrons.
D) The atomic mass is equal to the number of electrons.

Answers

Answer:

The correct option is  C) The number of protons is equal to the number of electrons.

Explanation:

Atoms are made up of particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom and form the nucleus, while electrons surround the nucleus. Electrons have a negative charge. The charge of the protons is positive and finally, the neutrons have no charge.

If the atom has no charge, this means that the total charge of the atomic nucleus, which is positive due to the presence of the protons, is equal to the negative charge of the electrons, so that it cancels out.

So, the correct option is  C) The number of protons is equal to the number of electrons.

The metric system is an international system of measurement that uses base units of meter for measuring distance, liter for measuring volume and grams for measuring mass.

The metric unit can be smaller or bigger than the base unit, hence, when using the metric system, the prefix shows the relationship between each unit to the base unit.

Explanation:

An object has a density of 16.3 g/mL and a volume of 0.46 L. Calculate the
mass of the object in pounds.

Answers

Answer:

The answer is

16.50 Ibs

Explanation:

To find the mass of a substance given the density and volume we use the formula

mass = Density × volume

From the question

Density = 16.3 g/mL

volume = 0.46 L

We must first convert the volume from L to mL

If 1 L = 1000 mL

Then 0.46 L = 0.46 × 1000 = 460 mL

Substitute the values into the above formula and solve

That's

mass = 16.3 × 460 = 7498 g

To convert the mass from g to lbs we use the conversion

1g = 0.0022 Ibs

If 1 g = 0.0022 Ibs

Then 7498 g = 7498 × 0.0022

We have the final answer as

16.50 Ibs
