Question 13

During each run of a chemical process, solutions containing the same solute are added at two different stages.

Stage	Volume of solution in $cm3\text{cm}^3$	Concentration in $mol/dm3\text{mol}/\text{dm}^3$
1	60.0	0.350
2	40.0	0.225

The process is modified so that one addition of a 0.120 mol/dm³ solution is used instead. The total amount of solute added during each run must remain unchanged.

Calculate the volume, in $cm3\text{cm}^3$ , of the replacement solution needed for each run of the process.
