Question

how many moles of methane are required to produce 220g of co2 gas after combustion?​

Answer 1

Answer:

5 moles CH3 is required to produce 20g CO2 gas

Explanation:

methane is CH3.

reaction goes like this

                                  CH3 +  7/4 O2 →  CO2 +  3/2 H2O

  moles of CO2 =  220/44  = 5 moles

by using stoichiometry , 1 mole CO2 require 1 mole CH3

                so        5 mole CO2 will require 5 mole CH3
