1. The problem statement, all variables and given/known data Write an equation in words to show relationship between mass concentration, molar concentration and molar mass and give a short explanation. 2. Relevant equations I understand that the equation is: molar mass = Mass concentration/Molar concentration 3. The attempt at a solution Where it says 'give a short explanation', what exactly does it want me to say? Does it have something to do with the equation no. moles = Mass/Mr?
