A 2.000 g sample of an unknown metal, M, was completely burned in excess [Solved]

So for every 2 moles of M2O3 you need to start with 4 moles of M. So if you ended up with 0.02224 moles M2O3 you stated out with 0.04448 moles M

So for every 2 moles of M2O3 you need to start with 4 moles of M. So if you ended up with 0.02224 moles M2O3 you stated out with 0.04448 moles M

An atomic mass of 44.96 corresponds to Scandium

So for every 2 moles of M2O3 you need to start with 4 moles of M. So if you ended up with 0.02224 moles M2O3 you stated out with 0.04448 moles M

As moles = mass / atomic mass
AM = mass / moles
= 2.000/0.04448
=44.96.

An atomic mass of 44.96 corresponds to Scandium
