1. What is the percent yield of MgO produced if 1.502 g of magnesium is ignited in air producing 1.699 g of MgO?

Expert Solution

1)

2 Mg + O2 ---------------> 2 MgO

48 g 32 g 80 g

1.502 ??

48 g Mg ----------------> 80 g MgO

1.502 g Mg --------------> ??

theoretical yield of MgO = 1.502 x 80 / 48 = 2.503 g

percent yield = (actual / theoretical ) x 100

= 1.699 / 2.503 ) x 100

percent yield = 67.87 %
