Moles of butane = mass/molar mass
= 8.14/58.12 = 0.14
Moles of Oxygen = 57.9/32 = 1.81
Reaction :
C4H10 + 13/2 O2 -> 4CO2 + 5H2O
1 mole butane require 13/2 mole O2
0.14 mole butane require 0.14×13/2 mole O2
= 0.91 mole O2
Since, we have more than this O2 thus butane is limiting reagent.
1 mole butane give 5 mole Water
0.14 mole butane give 5×0.14 = 0.70 mole water
= 0.70×18 g water
= 12.6 g water
% yield = 6.69×100/12.6 = 53.1%
