Its a reactant, comes on the left side of the yielding arrow.
Mass of Oxygen : 8 g
<h3>Further explanation</h3>
Given
48g of Magnesium
32g of Oxygen
Required
Mass of Oxygen
Solution
The ratio of Mg and O in MgO :
48 g : 32 g = 3 : 2
Total ratio = 3+2 = 5
So for 20 g MgO, mass of Oxygen :
=2/5 x 20 g
=8 g
Or
%mass O = 32/80 x 100%=40%
mass O in 20 g MgO =
40% x 20 g =8 g
