Calculation: how to make 25mL of a stock solution of 0.1M cupric sulphate

1. Work out the molecular weight of cupric sulphate from the formula: CuSO4.5H2O, given the following relative atomic masses (Ar) Cu = 63.57, S =32.06, O = 16 and H = 1.008

Record the calculation in your Practical Workbook and check your answer with a member of staff before proceeding. This is the mass of 1 mole of cupric sulphate.

2. How much cupric sulphate do you need to weigh out to make 25mL (0.025L) of a 0.1M solution?
