Question

A solution contains 60g of NaCl in 400g of water. Calculate the concentration in term of mass by mass percentage of the solution.​

Answer 1

Answer:

Explanation:

The formula for the % calculation:

percentage by mass = mass of solute  x 100% (mass of solute = 60g

                                mass of solution            mass of solution= 60g+400g=460)

 

% concentration = 60g   x 100%  =  6000    =13.04%

                          460g                    460

percentage concentration = 13.04%
