Question

If the empirical formula for a compound is NO2 and the molecular mass is 230.05 g/mol, what is the molecular formula for the compound? fast

Answer 1

Answer:
`\text{N}_(5)\text{O}_(10)`

Step-by-step explanation:

• The atomic mass of nitrogen is 14.0067 g/mol.
• The atomic mass of oxygen is 15.9994 g/mol.

This means the molecular mass of nitrogen dioxide is
`14.0067+2(15.9994)=46.0055` g/mol.

Dividing this molecular mass of the compound we need to find, we get that

`(230.05)/(46.0055) \approx 5`.

So, the final answer is
`\boxed{\text{N}_(5)\text{O}_(10)}`
