Question

calculate the volume of oxygen required to burn 500 ml of ethene gas at stp​

Answer 1

Answer:

We have

O

At STP we have

volume of 1 mole of gas = 22400 ml

so, moles of ethene in 20 ml of volume =

22400

1

∗20=0.00089moles

for, 1 mole of ethene we require 3 mole of oxygen

so, for 0.00089 mole of ethene we require oxygen = 0.00089×3=0.00267mole

hence, volume of oxygen require = 22400×0.00267=60ml
