Q1 5.3 Quantitative chemistry

A solution contains 0.50 mol of solute in 2.0 dm³ of solution. What is its concentration?

  1. 0.25 mol/dm³
  2. 1.0 mol/dm³
  3. 2.5 mol/dm³
  4. 4.0 mol/dm³
Show the answer and explanation

Answer: A. Concentration = amount of solute ÷ volume of solution = 0.50 ÷ 2.0 = 0.25 mol/dm³.
