Question #ce153

Answer 1

y will do nothing here. MF of X will be `C_5H_12`

Explanation:

1 mole of gas at r.t.p has a volume of 24 `dm^3`
Hence 60`dm^3` of `CO_2` is `60/24` mole = 2.5 mole
Now
0.5 mole HC produces 2.5 moles CO2 and 3 moles water

1 mole HC produces 5 moles CO2 and 6 moles water
So 1 molecule HC will contain 5 C atom and 12 H atom
since one molecule of CO2 contains 1 atom of C and one molecule of water contains 2 atoms of H
