Question

What is the molarity of a solution containing 45 grams of CaCl2 in 1.5 L of
water?

Answer 1

Data:

Mass of solute: 45 g

m.mass of solute: 110 g/mol

volume of water: 1.5 L

Step-by-step explanation:

percent w/v: 45/1500 *100

vol of solution: 3cm3=0.003dm3

M=g of solute/m.mass of solute*dm3 of sol

M= 45/110*0.003

M=14.85
