Question

An oxide of nitrogen has a molecular weight
of 30. Total number of electrons in one
molecule of the compound is
1) 15 2) 30 3) 45 4) 60​

Answer 1

Answer:

1

Explanation:

nitrogen oxide is formed by the nitrogen and oxygen.one molecule of nitrogen has 7 electrons and one molecule of oxygen has 8 electron ( half of molecular mass if molecule has no charge or neutral)

Answer 2

Answer:NO is the oxide having molecular weight 30

Explanation:

As Nitrogen has 7es and oxygen has 8 es the total es are 15

Therefore one molecule of the compound contain 15 es and

For n molecules 15×n
