0.25g of an organic compound containing carbon hydrogen and oxygen only were analysed by the combustion method.The increase in the weights of the U tube and the potash bulbs at the end of the operation were found to be 0.15g and 0.1837g respectively. Determine the percentage composition of the compound.

Explanation

To determine the percentage composition of the organic compound containing carbon, hydrogen, and oxygen, we will follow these steps:

### Step 1: Identify the mass of the compound and the products formed.
- Mass of the organic compound = 0.25 g
- Increase in weight of the potash bulb (mass of CO2 formed) = 0.1837 g
- Increase in weight of the U-tube (mass of H2O formed) = 0.15 g

### Step 2: Calculate the mass of carbon in the compound.
