Question

How do you define the concentration units mass percent and molarity?

Answer 1

`"Mass percent"` `=` `"Mass of component"/"Mass of compound"xx100%`

Explanation:

And `"molarity"` `=` `"Moles of solute"/"Volume of solution in litres"`

`"Mass percent"` is dimensionless, whereas `"molarity"` has units `mol*L^-1`.
