Determine the normality of 91.2 g of HCl in 4.3 L of solution. (Round to the nearest hundredth.)

mols HCl = grams/molar mass

M HCl = mols HCl/L HCl

What is the mass of 3 moles of barium? Round to the nearest tenth.

To determine the normality of a solution, you need to know the number of moles of the solute and the volume of the solution.

First, we need to calculate the number of moles of HCl. We can do this using the molar mass of HCl, which is 36.46 g/mol.

Number of moles of HCl = Mass of HCl / Molar mass of HCl

Number of moles of HCl = 91.2 g / 36.46 g/mol = 2.50 moles

Next, we need to calculate the normality of the solution. The normality (N) is defined as the number of equivalents of solute per liter of solution. For HCl, since it is a monoprotic acid, the number of equivalents is equal to the number of moles.

Normality (N) = Moles of solute / Volume of solution in liters

Normality (N) = 2.50 moles / 4.3 L = 0.58 N

Therefore, the normality of the solution is 0.58 N.
