1. What is the mass-percent of a solution that has 13.6 g of NaCl in 250.0 g of solution?

Mass percent = 5.44 %

Explanation:

Given dа ta:

Mass of solute (NaCl) = 13.6 g

Mass of solution = 250 g

Mass percent of solution = ?

Solution:

Formula:

Mass percent = mass of solute / mass of solution * 100

Mass percent = 13.6 g / 250 g * 100

Mass percent = 0.0544 * 100

Mass percent = 5.44 %
