0.27g of an organic compound gave on combustion 0.396 of `CO_(2)` 0.216g of `H_(2)O` 0.36g of the same substance gave 48.88 ml of `N_(2)` at 290K and 740mm pressure Calculate the percentage composition of the compound.

Explanation

To calculate the percentage composition of the organic compound, we need to find the percentage of carbon (C), hydrogen (H), and nitrogen (N) in the compound.

### Step 1: Calculate the percentage of Carbon (C)

1. **Calculate the number of moles of CO2**:
- Given mass of CO2 = 0.396 g
- Molar mass of CO2 = 12 (C) + 16*2 (O) = 44 g/mol
- Number of moles of CO2 = mass / molar mass = 0.396 g / 44 g/mol = 0.00900 moles
