Question 39

A de-icing liquid contains calcium chloride, CaCl2\mathrm{CaCl_2}CaCl2​.

A 400 cm3 portion of the liquid has a calcium chloride concentration of 2.00 mol/dm3.

Relative formula mass (MrM_rMr​) of CaCl2\mathrm{CaCl_2}CaCl2​ = 111.1

Calculate the mass of calcium chloride in this portion of the liquid.

Mass = ...... g
