Question

A 5.06 g sample of a laboratory solution contains 1.39 g of acid. What is the concentration of the solution as a mass percentage?

concentration: % acid

science chemistry

Answer 1

Answer #1

Mass percentage is given as,

Mass percent = (Mass of acid/mass of sample) × 100

Mass percent = (1.39/5.06)×100

= 27.5 %

Answer 2
