Question

4.4g of co2 and 2.24L H2 at stp are mixed in a container. The total number of molecules present in the container will be​

Answer 1

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.
