Calculate the weight and volume of air required for the complete combustion of 2kg of carbon.

(a) weight of air=5000g; volume of the air=17000l

(b) weight of air=17000g; volume of the air=15000l

(c) weight of air=5330g; volume of the air=17766.66l

(d) weight of air=8220g; volume of the air=1555.45l

I got this question in an online quiz.

The correct choice is (c) weight of air=5330g; volume of the air=17766.66l

Explanation: For calculation first the reaction is C+O2 → CO2.For this equation, 12 kg of c requires 32kg of oxygen for combustion then find for 2kg of carbon dioxide. At NTP 1g mole of oxygen occupies 22.4l then calculates for the weights of carbons that has calculated before then find volume of air by knowing that 100 parts of air contains 21 parts of oxygen.
