Question

a gas having formula ( co)x find x if vapour density is 70

Answer 1

vapor density*2=molecular mass of the compound.
molecular mass=140.

the molecular mass of carbon(C)= 12
the molecular mass of oxygen(O)=16
(C+O)x=140
(12+16)x=140
this is a linear equation in one variable.

28x=140
x=5
hope it helps!!!
