The molecular weight of an oxide of nitrogen is `30` .What is the number of electron is it ?

Options

A. `15`
B. `30`
C. `45`
D. `20`

Explanation

To find the number of electrons in the oxide of nitrogen with a molecular weight of 30, we can follow these steps:

### Step 1: Identify the atomic weights of nitrogen and oxygen
- The atomic weight of nitrogen (N) is 14 g/mol.
- The atomic weight of oxygen (O) is 16 g/mol.

### Step 2: Set up the equation for the molecular weight of the oxide
- The molecular weight of an oxide of nitrogen can be represented as:
