10 ml of 0.01M solution-
Molarity = moles/volume in L
so, moles of CuSO4 = Molarity*Volume in L
= 0.01M*0.01L = 0.0001moles
Molar mass of CuSO4 = 159.6g/mol
Mass of CuSO4 = moles*molar mass
Mass of CuSO4 = 0.016grams
So, weigh 0.016g of CuSO4 and dissolve in 10mL of water to make 0.01M solution.
Moles of CuSO4 = 0.02M*0.01L = 0.0002moles
Mass of CuSO4 = 0.0002mol*159.6g/mol = 0.0139grams
Dissolve 0.0139g of CuSO4 in 10mL water to make 0.02M solution.
3. 0.05M solution
Moles of CuSO4 = 0.05M*0.01L = 0.0005moles
Mass of CuSO4 = 0.0005moles*159.6g/mol = 0.0798grams
Dissolve 0.0798g of CuSO4 in 10mL water to make 0.05M solution.
4 . 0.06M solution
Moles of CuSO4 = 0.06M*0.01L = 0.0006moles
Mass of CuSO4 = 0.0006moles*159.6g/mol = 0.0958grams
Dissolve 0.0958 grams of CuSO4 in 10mL of water to make 0.06M solution.
