Question

An oxide of nitrogen has a molecular weight of 30. Total number of electron in one molecule of the compound

1) 15
2) 30
3) 45
4) 60​

Answer 1

Answer:

15 electrons.

Explanation:

NO is the only oxide of nitrogen with molecular mass 30.

So, just calculate the number of electrons in each atom in the molecule and add them.

In this case,

(7+8) = 15 electrons in 1 molecule of NO.
