Concentrated of aqueous sulphuric acid is 98 % H ₂ SO ₄ by mass and has a density of 1.80 ~g ~mL ⁻¹ Volume of acid required to make one litre of 0.1 M H ₂ SO ₄ solution is:
Options
- A16.65 ~mL
- B22.20 ~mL
- C5.55 ~mL
- D11.10 ~mL
Correct answer
C. 5.55 ~mL
Step-by-step solution
Molarity of H ₂ SO ₄ solution = 98 1000 98 100 1.84=18.4 Suppose V ml of this H ₂ SO ₄ is used to prepare 1 . of 0.1 M H ₂ SO ₄ aligned & V 18.02=1000 0.1 & ~V = 1000 0.1 18.02 =5.55 ml aligned
