The density of water is 1.0 g cm⁻³ and the density of glycerine is 1.3 g cm⁻³. Water is added to a measuring cylinder containing 40 cm³ of glycerine so that the density of the mixture is 1.1 g cm⁻³. Assume that the mixing process does not change the total volume of the liquid. What is the volume of water added?

1. A40 cm³
2. B44 cm³
3. C52 cm³
