please solve the question At STP 4 gm of gas occupies 2 litre then calculate V.D and molecular weight of gas?
Answers (1)
weight of 2 litre of gas = 4 gm
so weight of 22.4 litre = 4×22.4/2 = 44.8 gm
so molecular weight = 44.8 [ because weight of 22. 4 litre of any gas = molecular weight.]
we know vapour density = molecularweight/2=44.8/2=22.4
