Commercial grade hcl solutions are typically 39. 0% (by mass) hcl in water. Determine the molarity of the hcl, if the solution has a density of 1. 20 g/ml.

Answers

The molarity of the HCl, if the solution has a density of 1. 20 g/ml will be  12.83 M

% of HCL in the solution = 39.0 %

Density of the solution = 1.20 g/ml

Molarity of HCL = ?

Volume of the solution is not given so we take it as 1.0 L

Calculate the mass of silution

   mass = density × volume

    mass of solution = 1.20 g/ml × 1000 ml/L × 1.0 L

    mass of solution = 1200 g

Calculate the mass of HCl

38 %  = 38 g / 100 g

    mass of HCl = 1200 g (39 g / 100 g)

    mass of HCl = 1200g × 0.39 g

    mass of HCl = 468 g

Now calculate the number of moles of HCl

    number of moles = mass / molar mass

    number of moles of HCl = 468 g / 36.46 g

    number of moles of HCl = 12.83 mol

Calculate molarity

    molarity = number of moles of solute / volume L

    molraty HCl = 12.83 mol / 1 L

    molarity of HCl = 12.83 mol/L or 12.83 M

The density of WATER is 1gmL. Is the unlabeled clear liquid WATER? Why or why not? Pls explain

Answers

Yes, the unlabeled clear liquid water has a density of 1 gram/liter.

What is density?

Density refers to the mass of an object in unit volume of a substance. The formula for density can be represented as density = Mass / Volume. Density is expressed in grams / cubic centimeter. A common unit of measurement for water's density is gram per milliliter i.e. 1 g/ml or 1 gram per cubic centimeter i.e. 1 g/cm3.

So the exact density of water is not 1 g/ml, but rather less at 0.99 g/ml at 4° Celsius which is about 39.2° Fahrenheit. Water is an inorganic, transparent, odorless, and colorless chemical substance that is the main constituent of the hydrosphere of the earth and the fluids of all living organisms. It is important for all forms of life despite providing no food, energy, or organic micro-nutrients.

Bond order defines the number of chemical bonds between a pair of atoms and is a measure of a bond's stability.

A single covalent bond between two atoms has a bond order of 1, a double covalent bond has a bond order of 2, a triple covalent bond has a bond order of 3, and so on.To determine the bond order if the molecule has more than two atoms:Depict the Lewis framework.Count all the ties together.Determine the total number of bond groups spanning each atom.Subtract the quantity of atom-to-atom bonds from the total number of bond groups in the molecule.A molecule cannot form if the bond order is zero.More electron attraction is indicated by a high bond order. The atoms are bound together more firmly when there is a greater bond order. Because there is less electron attraction when the bond order is lower, the atoms are held together more loosely.Bond order also reveals the bond's stability. The more electrons binding the atoms together, the higher the bond order, and the higher the stability.

Answers

The carbon concentration of an iron-carbon alloy for which the fraction of total ferrite is 0.94 is 0.423.

Alloy is a substance that is composed of two or more metals or of a metal and a non - metal which are united among themselves by fusion in their molten state.

Iron-carbon alloy is an alloy than contains iron(metal) and carbon(non-metal) as its constituents.

Carbon concentration of iron-carbon alloy is calculated as follows:

W = {C (Fe₃C) - C₀} / {C (Fe₃C) - C}

⇒ 0.94 = (6.7 - C₀) / (6.7 - 0.022)

⇒ 0.94 × 6.678 = 6.7 - C₀

Oversize solid particles are those that cannot pass through the filter medium, and the fluid that does is known as the filtrate. Oversize particles can form a filter cake on top of the filter and also block the filter lattice, preventing the fluid phase from passing through the filter, a process known as blinding.

From the balanced reaction equation shown, the mole ratio of the sulfuric aid and the boron hydroxide is 3:2.

What is the mole ratio?

We know that in a chemical reaction, there are two sides; the reactants side and the products side. In the reactants side, what we have are the species that were combined to be able to get the products that we would have on the right hand side.

We have to recall that the way the reaction takes place and the formula of the products that are formed depends on the formula of the reactants as well as the mole ratio of the reactants. The mole ratio has to do with the stoichiometric coefficients of the reactants and the products in the reaction.

We now have to study the reaction closely so that we can be able to obtain the mole ratio of the sulfuric acid and the boron hydroxide.
