    Hey! I need some help please!

    Anyone know how I can calculate the quantity of matter, the mass concentration and the molar concentration? It is for a physics exercise!

    Thanks :)

    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!
