- Firstly, think of definition of moles (M), M = moles of species / L. 0.33 M = 0.33 moles HCl / L - Now, multiple your volume by molar concentration: 0.33 moles HCl / L x 0.70 L = 0.231 moles HCl It is helpful to convey the units with the calculations. In that way we can check ,the numerators and denominators cancel to give us the units of our answer.
