If one mole of the compound Al4C3 has a mass of 144g and one mole of carbon has a mass of 12g, calculate the relative atomic mass of the element aluminium.

4 Al + 3 C=144
4 Al + 3 *12=144

solve for Al

So C=36 which leaves 108 divided by 4 - so 1 mole of Al = 52 ---- is this correct?

If you get 52 from 108/4, you need a new calculator.

is the answer 27 by any chance

yes, 108/4 = 27

However, it isn't by chance. :-)

Long day! thanks for your help
