What is the molarity of 53.0 grams of HCl dissolved in 400.0 mL of water

Molarity = 3.625 M

Explanation:

Given dа ta:

Mass of HCl = 53.0 g

Volume of water = 400.0 mL (400/1000 = 0.4 L)

Molarity of solution = ?

Solution:

Number of moles of of HCl:

Number of moles = mass / molar mass

Number of moles = 53 g / 36.5 g/mol

Number of moles = 1.45 mol

Molarity:

Molarity = number of moles of solute / volume of solution in L

Molarity = 1.45 mol / 0.4L

Molarity = 3.625 M
