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, [tex]M_2O[/tex] then the chemical reaction will be expressed as:

[tex]4M + O_2 -> 2M_2O\\[/tex]

This shows that 4 moles of an unknown element M react with the oxygen element to produce the oxide [tex]M_2O[/tex]

Given the following parameters

Mass of M = 0.890 grams

Mass of [tex]M_2O[/tex] = 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
