Imagine you need to explain to a friend how to convert a value on a food label to one that is measured in grams. Assume the package of food has a mass of 1.0 pounds. write an explanation for how to use dimensional analysis to convert this value to one expressed in grams.

Answers

Answer:

453.592 grams

Explanation:

Given

Mass = 1 lb

Required.

Convert to grams using dimensional analysis

Represent 1 lb with x g

In unit conversion, we have that.

1 lb = 453.592 g

So:

Getting the equivalent of lb in g, we have:

x g = 1 lb * (453.592 g/ 1 lb)

x g = 1 * 453.592 g

x g = 453.592 grams

Hence:

The equivalent of 1 lb in grams is 453.592 grams

Express the following in regular notation:
3.4 x 10-1

A)O 34
B)O 0.34
C)0 3.4
D)0.00034

A because if you multiple it, you will be moving the decimal one time

How do you determine the charge of an isotope?

Answers

Answer:

If the protons in the atom outnumber the  electrons, the isotope has more positive charges than negative charges but If the number of electrons exceeds the number of protons, the ion charge will be negative.

Explanation:

The charge of an isotope is defined by how many more protons there are than electrons.

Or the other way around.

For example if there are 4 protons and 2 electrons, the ion charge is +2 because there are more protons.

If there are 4 electrons and 2 protons, the ion charge is -2 because there are more electrons.

does water in a glass have mass

Answers

Answer:

A glass of water, or 200 grams of water, therefore contains 6.6855 × 1024 water molecules. The total mass of the hydrosphere is about 1.4 × 1024 grams, and thus the total hydrosphere contains about 7 × 1021 glasses of water (with 200 grams of water in each).

Explanation:

Answer:

Just like solids, liquids also have their own characteristic density. ... Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter. The density of a substance is the same regardless of the size of the sample.

Matter is generally defined as any thing that has mass and occupies spaces. Matter is generally divided into three categories ; solid, liquid and gas. Water is a liquid, water has does have molecules, thus has a mass, and is suspended in an area such as water in glass.

SO YES WATER IN A GLASS HAS MASS :)

What is lunar phase ?

Lunar phase is the phase of moon which is viewed from the earth, the lunar phase is also known as moon phase is a shape of moon's directly sunlit portion and it can be expressed quantitatively.The current moon phase for today is the new moon phase.The moon is known as earth's only natural satellite and combinedly with earth it forms the earth-moon satellite system.

The size of moon is one quarter of earth in diameter. It is fifth largest satellite in the solar system. The distance of moon from earth is 384,400 km. The radius of moon is 1,737,4 km.  The gravity of moon is 1.62 m/sec^2.

The total surface area of moon is 3.793×10^7 km square and it's surface pressure is 10^-7 Pascal.There are total 8 phase of moon and these are new moon, first quarter, waxing gibbous, third quarter and waning crescent.

Therefore,Pluto's average distance from the Sun is about 3,666,000,000 miles and in inches it is 2.3227776e+14.

Calculate the mass of oxygen needed to react 10g of calcium to form calcium oxide. 2 Ca + O2→2 CaO

Answers

Answer:

Explanation:

1122 g CaO.

I hope I helped you! :)

The mass of oxygen needed to react 10 grams of calcium to form calcium oxide is 4.0 grams.

Given:

The reaction:

[tex]2Ca+O_2\rightarrow CaO[/tex]

Mass of calcium = 10 g

To find:

The mass of oxygen needed to react 10 grams of calcium to form calcium oxide.

Solution:

[tex]2Ca+O_2\rightarrow CaO[/tex]

Mass of calcium = 10 g

Moles of calcium = [tex]\frac{10 g}{40.078 g/mol}=0.25 mol[/tex]

According to reaction, 2 moles of calcium reacts with oxygen, then 0.25 moles of calcium will react with:

[tex]=\frac{1}{2}\times 0.25 mol=0.125 \text{ mol of }O_2[/tex]

Mass of 0.125 moles of oxygen gas:

[tex]0.125 mol\times 31.998 g/mol=3.99975 g\approx 4.0 g[/tex]

The mass of oxygen needed to react 10 grams of calcium to form calcium oxide is 4.0 grams.
