1 Basic Concepts of Chemistry
A gaseous mixture contains CH4 and C2H6 in equimolar proportion. The weight of 2.24 litres of this mixture at NTP is .. 1) 4.6g 2) 1.6g 3) 2.3g 4) 23g
Solution
equimolar will occupy same volume i.e. 1.12 L each 22.4 L=1 mole 1.12 L=0.05 mole Molecular weight of CH4=16g, ∴0.05 mole=0.8 g Molecular weight of C2H6=30g, ∴ 0.05mole=1.5g Total weight=0.8 +1.5=2.33g
