Calculate the freezing point depression for a solution containing 456g calcium phosphate in 3280g water. 4.185

Expert Solution
Step 1

Given:

Mass of Ca3(PO4)2 = 456 g

Molar mass of Ca3(PO4)2 = 310.18 g/mol

Mass of H2O = 3280 g = 3.28 Kg

Freezing point of water = 0 oC

Molal depression constant = Kf = 1.86 °C/m

Ca3(PO4)2 dissociates into 3 Ca+ and 2 PO4- ions. So, there are total 5 ions in the solution. therefore, van 't Hoff factor(i) = 5.

Step 2
