Explanation:
mg + o ---------->mgo
so, 6 U + 4 U ---------------> 10 U
= 6g + 4g -----------> 10g
as per balanced equation,
6g of magnesium -------> 10g of magnesium oxide
9.6g of magnesium ----> xg of megnsium oxide
(9.6)(10g)/6 ---------> xg
16g ---------> x
since 16 grams of magnesium oxide can be obtained from 9.6 grams of magnesium
