Answer:

option b

Explanation:

Answer 2

Answer:

A) 27

Explanation:

Since the formula is X2O3  

We can find the molecular mass of each element  independently

so First molecular mass of X = 2x

molecular mass of oxygen = 16*3 =48

Now the ratio is given as 9:8

so equating  2x/48 = 9/8

x = 27
