Question

calculate the volume of oxygen required for the complete combustion
of 8 8 g of propane

Rati Singh · Accepted Answer

Solution-

The balanced
equation of Combustion of propane is-

C3H8 +
5O2 → 3CO2 +
4H2O

The molecular mass of propane = 44 gm
The volume of 5 O2
at STP = 5 × 22 4 = 112 L
So, 44g of propane requires 112 L of oxygen for
complete combustion

8 8 gm of propane requires
oxygen for combustion = 11244×8 8 = 22 4 L

calculate the volume of oxygen required for the complete combustion of 8.8 g of propane
