Question

Amount of H2SO4 in 2 litres, having 28% m/v is:
A. 14g
B. 49g
C. 560g
D. 144g

Answer 1

Answer ⇒ Option (c). 560 gm.

Explanation ⇒ Given,

Mass of Sulphuric acid/Volume of solution = 28%

This means, mass of the sulphuric acid in 100 mL of the solution is 28 gm.

Also,

Volume of the solution is 2 L.

Thus,

2000 L or 2 L of the solution will have an mass of Sulphuric acid as 28/100 × 2000

= 28 × 20

= 560 gm.

Hence, mass of the sulphuric acid is 560 gm.

Option (c). is correct.

Hope it helps.
