Solution

Dear student,

Gram molar volume is the volume occupied by 1 mole of a substance at STP. The value of this volume is 22.4 Lit.
For calculation purpose, there is one simple formula that will solve the maximum number of questions and that is-

$M o l e = \frac{W e i g h t o f s u b s \tan c e}{M o l a r m a s s o f s u b s \tan c e} = \frac{N u m b e r o f m o l e c u l e s}{A v o g a d r o n u m b e r} = \frac{V o l u m e o c c u p i e d b y m o l e c u l e}{22.4}$
In the above formula, there are 5 variables, so you can find any of the variables that is asked in the question by simple interlinking with the given data.

Regards
