Question
Equal masses of SO2 and O2 are placed in a flask at STP choose the correct statement.
Options
A.The number of molecules of O2 are more than SO2
B.Volume occupied at STP is more for O2 than SO2
C.The ratio of number of atoms of SO2 and O2 is 3 : 4.
D.Moles of SO2 is greater than the moles of O2.
Solution
Let W gas of SO2 and O2 are taken
moles of SO2 =
moles of O2 =
molecules of O2 =
molecules of SO2 =
hence molecules of O2 > molecules of SO2
since moles of O2 > moles of SO2, hence volume of O2 at STP > volume of SO2 at STP.
moles of SO2 =
moles of O2 =
molecules of O2 =
molecules of SO2 =
hence molecules of O2 > molecules of SO2
since moles of O2 > moles of SO2, hence volume of O2 at STP > volume of SO2 at STP.
