Question 5

A grower must add exactly 0.00500 mol of calcium nitrate to a hydroponic tank. The table shows four samples of calcium nitrate solution the grower could add.

Sample	Volume of solution	Concentration
P	20.0 cm³	0.300 mol/dm³
Q	25.0 cm³	0.200 mol/dm³
R	40.0 cm³	0.100 mol/dm³
S	50.0 cm³	0.0100 mol/dm³

Which sample provides exactly the amount of calcium nitrate the grower needs?
