The molar mass of M is 0.225g/mol and the element M is Hydrogen

If a metal M combines with an oxygen element to form the oxide, $M_2O$ then the chemical reaction will be expressed as:

$4M + O_2 -> 2M_2O\\$

This shows that 4 moles of an unknown element M react with the oxygen element to produce the oxide $M_2O$

Given the following parameters

Mass of M = 0.890 grams

Mass of $M_2O$ = 0.956 grams

Get the molar mass of M:

Molar mass = Mass/number of moles

Molar mass = 0.890/4

Molar mass = 0.225g/mol

Hence the molar mass of M is 0.225g/mol and the element M is Hydrogen
