A technician has two calcium nitrate solutions. Solution P was made by dissolving 0.0250 mol of calcium nitrate and making the volume up to 200 cm3 with water. The bottle holding solution Q is labelled 18.5 g/dm3. Mr M_r\,Mr of calcium nitrate = 164.
Determine which solution is more concentrated. Give the difference between the two concentrations in g/dm3\text{g/dm}^3g/dm3.
