Pure sulfuric acid is a liquid of 1.84 density. What volume of it would be required to prepare 250 cm3 of 2.0 M solution?

(H = 1, S = 32, O = 16)

  • A 2.00
  • B 2.66
  • C 3.00
  • D 3.66
  • E 4.00

The correct answer is B. 2.66

1000 cm3 of 1 m H2SO4 contains 98 gm of H2SO4

250 of 1 m H2SO4 (98)/(4) x (2)/(10) = 4.9 gm

But density = (mass)/(volume)

Volume = (Mass)/(Density) (4.90)/(1.84) = 2.66
