A metal M react next to nitrogen to form a compound have the formula M3N.?

A metal M reacts with nitrogen to form a compound have the formula M3N.
15.46 g of the metal produce 25.86 g of the compound. Calculate the molar mass of the metal.

Enter a numeric answer only, no units.
Answers:
6 M + 3 N2 = 2 M3N

mass N = 25.86 g - 15.46 g= 10.4 g
moles N = 10.4 g/ 14.0067 g/mol=0.743

the ratio between N and M is 1 : 3
moles M = 3 x 0.743 /1 =2.23

molar mass M = 15.46 g / 2.23 mol= 6.94 g/mol

M is Lithium and the aversion is

6 Li + N2 = 2 Li3N
