Question

A mixture consisting or 0.10 moles of N2 0.05 moles of O2 , and 0.20 moles of CH4 and an unknow
amount of CO2 occupied a volume of 9.6 L at 27°C and 1.0 atm pressure. How many moles of CO2
are there in this sample?
(A) 0.04 mol (B) 0.39 mol (C)0.05 mol (D) 0.10 mol​

Answer 1

Answer:

PV= nRT

9.6×1. = (0.1+0.05+0.2 +n CO2) RT

n CO2 =. (9.6 /RT -. 0.35 ) mole CO2
