Hi there!

I was looking for the same answer as you and I found a great website for students! The purpose is to post your homework and to gel help :)

I found there that to calculate the quantity of matter the formula is n = m/M, the molar concentration is C = n/V and the mass concentration is Cm = M x C

You can check it out here : www.digischool.co.uk/homework/year-11/physics

Hope I helped you :) See you!
