How many grams of Ca(OH)2should the chemist add to make 1 liter of 0.5 M Ca(OH)2 solution?

Answer 1

Molarity = Mol / Vol = (Mass/Molecular mass) / Vol

Molarity = 0.5M

Molecular mass of Ca(OH)₂ = 74.093 g/mol

Vol = 1 L

Mass = Molarity * Molecular mass * Vol = 0.5 M * 74.093 g/mol * 1 L = 37.05 g
