[1]
A

A solution of concentration 1.0 mol/dm31.0\ \text{mol/dm}^31.0 mol/dm3 holds 1.0 g1.0\ \text{g}1.0 g of solute in each dm3\text{dm}^3dm3 of solution.

B

Two solutions with the same concentration in g/dm3\text{g/dm}^3g/dm3 have the same concentration in mol/dm3\text{mol/dm}^3mol/dm3.

C

A solution of concentration 1.0 mol/dm31.0\ \text{mol/dm}^31.0 mol/dm3 holds 0.50 mol0.50\ \text{mol}0.50 mol of solute in 500 cm3500\ \text{cm}^3500 cm3 of solution.

D

Adding more water to a solution increases the concentration of the solution in mol/dm3\text{mol/dm}^3mol/dm3.
