Question

What is the weight of oxygen required for the complete combustion of 2.8 kilograms of Ethylene

Answer 1

Answer:

So to oxidise 2.8kg of ethylene we require 9.6kg of oxygen.

Explanation:

C2 H4 (ethylene)+ 3O2 - 2CO2+ 2H2O

To oxidise 1 mol of ethlene we require 3 moles of oxygen.

∴ For oxidising 28g of ethylene we require (3×32)g of oxygen

∴ For oxidising 2800g (2.8kg) of ethylene we require (96×100)g of oxygen

∴For oxidising 2.8kg of ethylene we require 9600g of oxygen

So to oxidise 2.8kg of ethylene we require 9.6kg of oxygen.

Hence we need 9.6 kg of oxygen
