Question

the density of a gas at stp is 2g/l then its molecular weight is​

Answer 1

Answer: Given that,

The condition at STP are :

P=1 atm, T=273.15K, R= 0.0821 L atm mol K. (P' - is row)

Explanation:

Using the equation,

P' = PM/RT

M=P'RT/P

M= 1.8×0.0821× 273.15/1

M= 40.36 is equal to 44.8g

The Molecular weight is 44.8g
