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 %

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
