Q97) A gaseous mixture contains CH4 and C2H6 in equimolar proportion. The weight of 2.24 litres of this mixture at NTP is ..


equimolar will occupy same volume i.e. 1.12 L each
22.4 L=1 mole
1.12 L=0.5 mole
Molecular weight of CH4=16g, ∴0.5 mole=0.8 g
Molecular weight of C2H6=30g, ∴ 0.05mole=1.5g
Total weight=0.8 +1.5=2.33g
Answer: (c)
