Calculate the amount of CuSO4•5H2O required to make 25 mL of a 0.45 M solution of CuSO4.

Mass = 1.76 g

Explanation:

Given dа ta:

Volume of solution = 25 mL

Molarity = 0.45 M

Amount of CuSO₄.5H₂O = ?

Solution:

Molarity = number of moles / volume in litter

Number of moles = Molarity * Volume in L

Number of moles = 0.45 M * 0.025 L

Number of moles = 0.011 mol

Mass of f CuSO₄.5H₂O:

Mass = Number of moles * molar mass

Mass = 0.011 mol * 159.6 g/mol

Mass = 1.76 g
