Question

30 grams of copper sulphate is dissolved in 170 grams of water find m/m% of the solution

urgent tell me fast ​

Answer 1

Answer:

Mass of solute = 20 g

Volume of solution = 500 ml

Mass by volume percentage =

Volume of solution

Mass of solute×100

=

500

20×100

=4%

Answer 2

Answer:

0.15%

Explanation:

Given:

Copper sulphate (solute) = 30g

Water (solvent) = 170g

•°• Solution of copper sulphate & water = solute + solvent

= 30g + 170g

= 200g

=> Mass by mass% of the solution = mass of solute

mass of solution

= 30g

200g

= 3g

20g

= 0.15%

.°. The mass by mass% of the solution = 0.15%

Hope it helps..
