Hi Vikash!
As you mentioned that oxide of metal has 40% by mass of oxygen, means 40 grams of oxygen. So, amount of metal 'm' in metal oxide= 60 grams.
Therefore, number of moles of metal 'm' = 60/24 =2.5
And number of moles of oxygen = 40/16 =2.5
Hence the ratio of moles of 'm' and O is 1:1
So, the empirical formula is MO.
Thankyou!
