Question

Calculate the volume needed to dissolve 11.2g CuSO4 to prepare 0.140M?

Answer 1

How many moles do you have in 11.2 g?
mols = grams/molar mass.

MCuSO4 = moles CuSO4/L CuSO4
You have M and moles, solve for L.

Answer 2

Calculate the volume required to dissolve 11.2 g of CuSO4 to prepare a 0.140M solution.

Answer 3

Calculate the volume required to dissolve 11.2 g of CuSO4 to prepare a 0.140M solution

Answer 4

Let‘s walk through the steps. We know that M = moles of solute/L of solution. To find the number of moles of CuSO4, we need to put 11.2 grams over its atomic mass, 159.62 grams. The quotient is 0.07, meaning we have .07 moles. We also know that the final molarity is 0.140M.
We can rearrange the equation to be L of solution = moles of solute/molarity (M). Using this, let‘s plug in the numbers:
L = 0.07/0.140
L = 0.5
You‘ll need 0.5 liters of solution, or 500 milliliters.
