Question

How to make 500.mL of 0.20M CuSO4 solution. (include all steps and calculations )

Briefly.

Answer 1

Answer -

Molarity of CuSO4 = 0.20 M

Volume required = 500 mL or 0.5 L [1 mL = 0.001 L]

Molar Mass of CuSO4 = 159.609 g/mol

We know that,

Molarity = Moles / Volume in L

So,

Moles of CuSO4 = 0.20 M * 0.5 L

Moles of CuSO4 = 0.1 mol

Also,

Moles = Mass / Molar Mass

So,

Mass = Moles * Molar Mass

Mass of CuSO4 = 0.1 mol * 159.609 g/mol

Mass of CuSO4 = 15.96 g

So,

Take 15.96 g of CuSO4 and add 500 mL of water to get the required solution.
