A compound gave the following data:
`C = 57.82%,0 = 38.58% ` and the rest hydrogen. Its relative molecular mass is 166. Find its empirical formula and molecular formula.
`[C = 12,0 = 16, H = 1]`

Explanation

To solve the problem, we need to find the empirical and molecular formulas of a compound given the percentage composition of its elements and its relative molecular mass. Let's break down the steps:

### Step 1: Determine the mass of each element
Given the percentages:
- Carbon (C) = 57.82%
- Oxygen (O) = 38.58%
- Hydrogen (H) = 100% - (57.82% + 38.58%) = 3.60%
