Quantity of matter, mass concentration, molar concentration

[gwenshann]

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

Hope I helped you :) See you!
