If 32.5 grams of cao are dissolved in 212 grams of water, what is the concentration of the solution in percent by mass? 6.52% cao 8.67% cao 13.3% cao 15.3% cao

Concentration of solution in percent by mass is 13.3% CaO

Explanation:

% by mass =

Here solute is CaO and solvent is water.

So, mass of solution = (mass of solute)+(mass of solvent)

                                  = (mass of CaO)+(mass of water)

                                   = 32.5 g + 212 g

                                    = 244.5 g

So, Concentration of solution by percent mass = = = 13.3 %
