An oxide XO\(_2\) has a vapour density of 32. What is the atomic mass of X?

vapour density =32
2*vd=rmm
rmm=32*2
=64

[XO2]n =64
X+32=64X=64-32
X=32

Relative molecular mass=2 ×vapour density =2×32»64
XO2= X+2(16)
64=X+32
X=32(collecting like terms)

my bad 😔 all I was saying is
we're simply finding the MASS NO.
they used the word atomic mass to

it's not 16×2 to give 64 but 32×2 to give 64

I actually thought relative molecular mass is the same as atomic mas

Mehnnn
the simple fact is they we ought the MASS NO., the whole atomic mass English was just for confuse
