Solution 45P :

Step 1:

Formula to find mass percent :

Mass percent = 100 %

Mass Solution = Mass solute + Mass solvent

Let’s consider 1st row :

Mass solute = 15.5 g

Mass solvent = 238.1 g

Mass Solution = ?

Mass percent = ?

Mass Solution = 15.5 g + 238.1 g

Mass Solution = 253. 6 g

Mass percent = 100 %

Mass percent = 6.11 %
