We’re being asked to calculate the mass of NaCl in a 15.00% by mass solution of NaCl.


We’re given the mass percent of the solution and we're going to use the mass percent formula shown below:

mass percent=mass componenttotal mass×100


Since we are dealing with a solution, we can rewrite the equation as:

% mass=mass solutemass solution×100


Calculate the mass of NaCl:
