Question

20 ml of concentrated sulphuric acid is added to 180 ml of water. What is the concentration of the solution

Answer 1

Given,

Volume of Sulphuric Acid (v) = 20 mL

Volume of Water = 180 mL

Volume of Solution (V) = (20+180) mL

= 200 mL

Concentration of Solution = v/V*100%

= 20/200*100%

= 10%
