16. A 4.37 g sample of a certain diatomic gas occupies a volume of 3.00-L at 1.00 atm and a temperature of 45°C. Identify the gas. Anyone please help?
n (no of moles) = m(mass)/M (Molecular wt. )
R in Lt-atm scale 0.08205736(14)L-atm /K-mol ~ 0.082
So, fitting values
Now the only diatomic gas which has closest molecular mass is Fluorine (
