Question 7

Mole Concept and Stoichiometry

If 1 litre of 2.2M sulphuric acid is poured into a bucket containing 10 litres of water, and the resulting solution mixed thoroughly, the resulting sulphuric acid concentration will be

  1. A.2.2 M
  2. B.1.1 M
  3. C.0.22 M
  4. D.0.11 M
  5. E.0.20 M
Show the answer and explanation

Answer: E (0.20 M)

Explanation

The 2.2 mol of acid end up in 1 + 10 = 11 litres, so the concentration is 2.2 ÷ 11 = 0.20 M.
