Question

The atomic mass of an element X is 32 and its vapour density is 128. The atomicity of X is -

​

Answer 1

Answer:

vapour density =x×32

x=128/32=4

so atomicity is 4

Answer 2

Answer:

8

Explanation:

1. Lets first look how to calculate atomicity:-

$Atomicity = \frac{molecular mass}{atomic mass}$

2. Since we already know the atomic mass, we now have to calculate the molecular mass.  Now let's look at how to calculate molecular mass:-

$Molecular mass = 2 * vapour density$

Therefore, the molecular mass = 2 * 128

                                                   =  256

3. Now that we got molecular mass, we can finally insert this into the formula:-

$Atomicity = \frac{256}{32} \\\\Atomicity= 8$

Hope this helped.
