Expert Solution

Step 1: Formula

Mass percent of component in a solution is the mass of the component present per 100 g of the solution.

So, the formula for the mass percent = $fraction numerator M a s s space o f space t h e space c o m p o n e n t over denominator T o t a l space m a s s space o f space t h e space s o l u t i o n end fraction cross times 100 percent sign$ .
