Question

Volume at NTP of oxygen required to completely burn 1 kg of
coal(100% carbon) is ??

Raj Shukla · Answer

Equation: C + O2 ? CO2 1mol C will react with 1 mol O2 Mass ratio
12:32 1kg coal will require 1*32/12 = 2 667kg = 2,667 g O2 Molar
mass O2 = 32g/mol 2,667g = 2667/32 = 83 34mol Ar NTP 1 mol = 24L 83
34 mol = 83 34*24 = 2000L You ask about NTP = my understanding is
that at NTP 1 mol gas = 24L But at STP , 1 mol gas = 22 4L At STP ,
83 34mol = 83 34*22 4 = 1,867L OR 1 86*10^3 L Volume of O2 required
art STP = 1 86*10^3 L
