If the total mass of the mixture is 240.5 g, what masses of CaCl2 and water should be used? Mass of CaCl2 Number g CaCI Mass of water Number

Explanation / Answer

m/m% = which means 32.5 g of cacl2 present in 100 g solution.

mass of CaCl2 = 240.5*32.5/100 = 78.16 g

mass of water = 240.5-78.16 = 162.34 g
