a 4 06 g sample of a laboratory solution contains 1.41 g of acid. what is the concentration of the solution as a mass percentage.
Homework Answers
From the given data, mass of acid (solute ) = 1.41g
We know that,
mass percentage =(mass of solute/mass of solution)×100
Mass percentage = (1.41g/4.06g)×100
= 34.73%.
If given mass of solution = 406g, then
Mass percentage = (1.41g/406g)×100
= 0.35% .
