Calculate the volumes at STP occupied by `6.023 xx 10^(23)` molecules of a gas X.

Explanation

[1 mole of any substances contains `6.023 xx 10^(23)` number of molecules [Avogadro's number]
(a) `6.022 xx 10^(23)` molecules occupied 22.42 `cm^(3)` (its) `=(22.4 xx 6.023 xx 10^(22))/(6.023 xx 10^(23))` = 2.24 lits.
