A solution of CuSO4 is labelled 0.01 M. How much CuSO4 in grams, must be used to make 1 liter of solution?
Mkey [24]

Correct answer: C) 1.6 g

Molarity is the moles of solute present per liter solution.

The given molarity of the solution is 0.01 M.

Volume of the solution = 1 L

Calculating the moles from molarity and volume:

Moles of CuSO_{4} = 0.01 \frac{mol}{L} * 1 L = 0.01 mol CuSO_{4}

Converting moles to mass of copper sulfate:

0.01 mol CuSO_{4} * \frac{159.61 g CuSO_{4}}{1 mol CuSO_{4}} = 1.6 g CuSO_{4}
