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:
Since we are dealing with a solution, we can rewrite the equation as:
Calculate the mass of NaCl:
What mass of NaCl is contained in 24.88 g of a 15.00% by mass solution of NaCl in water?
