What's the difference between molarity, percent by mass, and parts per million?
Need help with a lab for chemistry.
By the way I know the equations. Just looking for the difference between these three.

molarity = moles per litre
percent by mass = grams substance per 100 grams of total stuff
parts per million or ppm = grams per million grams or mg per kg or microlitres per litre etc.
