You need to make 4200 mL of 0.450 M CuSO4. How many grams of CuSO4 do you need?

• Chemistry -

How many moles do you need? That is M x L = mols = 0.450 x 4.2L = ?
Then mols = grams/molar mass.

• Chemistry -

302.4 grams

• Chemistry -

I get 0.450M x 4.2L x 159.61 = 301.66 = 302g to three significant figures
