volume occupied by 1g-atom of a gas at STP is 5.6 L. Calculate the atomicity of gas molecules

Open in App

Solution

Dear student,

At STP the volume of gas for 1g-atom = 22.4 L
the volume of gas given at 1g-atom = 5.6 L
for the calculation of atomicity of gas we apply a general formula as :

Atomicity = $\frac{M o l e c u l a r v o l u m e o f 1 g - a t o m g a s a t S T P}{G i v e n v o l u m e o f g a s a t S T P}$
= $\frac{22.4}{5.6}$
= 4

Therefore, the atomicity of a gas is 4
