1. 2moles of S is required to react completely with 3moles of O2

Hence, (2x1)/3 moles of S is required to react completely with 1mol of O2

= 0.67mol


2. 3mol of O2 --> 2mol of SO3

1mol of O2 --> (1x2)/3 mol of SO3


= 0.67mol


3. 3moles of O2 --> 2moles of SO3

x moles of O2 --> 0.80 mol of SO3


x = (3x0.80)/2 = 1.2moles


Hence, 1.2 moles of O2 is required to produce 0.80mol of SO3
