Question

A solution containing 35 g of copper sulphate dissolved in 395 ml of water calculate the mass by mass percentage of the solution

Answer 1

Answer is given in the attachment

Answer 2

Answer:

Mass by mass percentage of a solution = [(Mass of solute) / (Mass of solution)] X 100

Here, mass of solute ( cuSo4) = 110g

Mass of solution = 550 g

Therefore mass by mass percentage of solution = (110 X 100) / 550

= 20%
