Question
Weight of ethane which occupies the same volume of STP as 9.6g of methane is:
- 6 gm
- 10 gm
- 14 gm
- 18 gm
Hint:
Same mole of both methane and ethane would have same volume at STP.
The correct answer is: 18 gm
Mass of one mole of methane is 16g, 9.6g of methane is 0.6 mole.
Same mole of both methane and ethane would have same volume at STP.
Mass of 0.6 mole of ethane 18g.
18g of ethane occupies the same volume of STP as 9.6g of methane.
