Write the molecular formula for a compound with the possible elements C, H, N and O that exhibits a molecular ion at M

Explanation:

From the given information, since the molecular mass of the ion M+ is not given;

Let's assume M+ = 58.0423

So, by applying the 13th rule;

we will need to divide the mass by 13, after dividing it;

The quotient n = no. of carbon; &

The addition of the quotient (n) with the remainder r =  no. of hydrogen.

So;

So;

From the given information; we have oxygen present, so since the mass of oxygen = 16, we put oxygen in the molecular formula by removing . Also, since the mass is an even number then Nitrogen is 0.

So, we have:

i think it is true since you can test the answer and can use observations to complete it.
