The ratio of number of oxygen atoms to bromine atoms in the product Q is _____ x 10^-1.

Question

\(\xrightarrow {HNO_3 .H_2SO_4} \underset {major\, product}{P} \xrightarrow {2\,Br_2, Fe} \underset {major\,product}{Q}\)

The ratio of number of oxygen atoms to bromine atoms in the product Q is _____ \(\times 10 ^{-1}.\)

Answer 1

Correct answer is : 15

In Q Total oxygen atoms = 3 

Total Bromine atoms = 2

ration \(= \frac {3}{2} = 1.5 \times 10 ^{-1}\)
