3.4 Using concentrations of solutions in mol/dm3

Question 13

Solution E contains potassium nitrate, $KNO3\text{KNO}_3$ , at 0.100 mol/dm³. Solution F contains sodium chloride, $NaCl\text{NaCl}$ , at 0.100 mol/dm³. The relative formula masses are $KNO3=101\text{KNO}_3 = 101$ and $NaCl=58.5\text{NaCl} = 58.5$ . Which statement is correct?

[1]

The concentrations in $mol/dm3\text{mol/dm}^3$ are the same, and E has the higher concentration in $g/dm3\text{g/dm}^3$ .

The concentrations in $mol/dm3\text{mol/dm}^3$ are the same, and F has the higher concentration in $g/dm3\text{g/dm}^3$ .

The concentrations in $g/dm3\text{g/dm}^3$ are the same, and E has the higher concentration in $mol/dm3\text{mol/dm}^3$ .

Solution E has the higher concentration in $mol/dm3\text{mol/dm}^3$ and the higher concentration in $g/dm3\text{g/dm}^3$ .
