Chemistry - PYQ 2024

 Q. Mass of methane required to produce 22 g of CO2 after complete combustion is ____g. ( Given: molar mass in g mol-¹, c=12.0 ,H=1.0, O=16.0

                                                        (JEE 2024)

1. 8


2. 32


3. 4


4.None of these 

(8) 

CH4 + 2O2→ CO2 + 2H2O

 Moles of CO2 = 22 = 0.5 44 

So, required moles of CH4 = 0.5 

Mass = 0.5 × 16 = 8gm
