In class 11th in the chapter of
mole concept
of
chemistry
, we study a formula of
vapour density
which is :-
Vapor density = (molecular weight) / 2
Now the formula mass of CO is = 28
Vapour density of the gas = 70
Therefore, by using the above formula -
Molecular weight of gas = 702 = 140
And we have to find x
So, x = 140/28 = 5
So the value of x in the above question is 5
Vapor density = (molecular weight) / 2
Now the formula mass of CO is = 28
Vapour density of the gas = 70
Therefore, by using the above formula -
Molecular weight of gas = 702 = 140
And we have to find x
So, x = 140/28 = 5
So the value of x in the above question is 5
