Question

Calculate the volume of air containing 21 oxygen

Answer 1

Explanation:

considered oxygen as O2 not O. SO2+ half O2 ------> SO3 22.4 l requires 11.2 l oxygen gas 294 cc will require 147 cc of O2 gas let air volume= x cm cube 0.21*x=147 x=700 cm cube If the answer is not what you want then consider O2 as O atoms and solve

Answer 2

HERE IS YOUR ANSWER

I considered oxygen as O2 not O. SO2+ half O2 ------> SO3 22.4 l requires 11.2 l oxygen gas 294 cc will require 147 cc of O2 gas let air volume= x cm
