Question

if 11.2l of gas is released from 44g of carbon dioxide gas in a container to stp, how many more gases will remain in that container?

Answer 1

Answer:

No.of moles of CO2 in 4.4 g CO2=4.4/44=0.1 mole.

No.of moles of H2-gas in 2.24 liters at STP=2.24/22.4= 0.1 mole.

So total moles of H2 and CO2 gas are =(0.1+0.1)=0.2 moles.

Total number of Molecules in the container=0.2 x 6.022 x 10^23 =1.2044 x 10^23.
