Answer #1

Mg +       S   -------------------> MgS

24 g          32 g                           56 g

12.1525 g      48.099 g                        ??

here limiting reagent is Mg.so product formed based on that.

24 g of Mg ------------------   gives 56 g of MgS

12.1525g of Mg ----------------> ?? of MgS

mass of MgS = 12.1525 x 56 / 24

                        = 28.36 g

mass of MgS = 28.356 g
