Answer:
Molarity = 3.625 M
Explanation:
Given data:
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
