Question

If a 0.075 liter solution contains .0877 moles of `CuCO_4`, what is the molarity?

Answer 1

Well, let's make the solute `CuCl_2`...........Why? Because there ain't no such beast as `CuCO_4`. (There are copper carbonyls, but I don't think that's what you mean.)

Explanation:

`"Molarity"` `=` `"Moles of solute"/"Volume of solution"`

`=(0.0877*mol)/(0.075*L)=1.17*mol*L^-1`..............
