Question

If 0.0262 mol of cacl2 is dissolved in water to make a 0.520 m solution, what is the volume of the solution?

Answer 1

Cacl2 dissolve in water according to the following equation

Cacl2 + H2O = Ca(OH) + Hcl
Volume= moles/molarity
The reacting ratio between CaCl2 to Ca(OH) is 1:1
therefore moles of solution is also 0.0262 moles hence volume is =
0.0262mol/ 0.52mol/l = 0.0504L or50.4ml
