Question

the element nitrogen and magnesium react to give magnesium nitride according to the balanced equation
N2 + 3Mg = Mg3N2

suppose you have 0.3616 mol of n2

1-how many moles of mg are needed for complete reaction?
2-what mass of Mg3N2, in grams can be produced? ( the molar mass of Mg3N2 is 100.9284 g/mol)

- please show step to step and the answere please becuase i need to go check it and see how you did it

thanks
