Question

determine the mass by mass percentage concentration of 100 grams salt solution which contains 20 grams salt?

Answer 1

Heya,

Mass by mass percentage = Mass of the solute/mass of the solution

Given,

Mass of solute = 20 grams

Mass of solution = 100 grams

Mass by mass % = 20/100

=1/5 = 0.2%

Answer 2

Mass of salt = 20 g

Mass of salt solution = 100 g

Mass percentage = mass of salt / mass of salt solution×100

= 20/100×100 = 20%

Hope it may helps you...
