Question

What’s the percent by mass of 3.55g NaCL in 91.55g of solution

Answer 1

Answer:

3.88%

Explanation:

Given parameters:

Grams of solute = 3.55g of NaCl

Grams of solution = 91.55g of solution

Mass percentage

of NaCl(%) = grams of solute/grams of solution x 100

Mass percent = 3.55/91.55 x 100

Mass percent = 3.88%
