The following experiment was performed in order to determine the formula of a hydrocarbon. The hydrocarbon X is purified by fractional distillation. 0.145 g of X were heated with dry copper (II) oxide and `224 cm^(3)` of carbon dioxide was collected at S.T.P
Calculate the empirical formula of X by the following steps :
Deduce the ratio of atoms of each element in X (empirical formula).

Explanation

To determine the empirical formula of the hydrocarbon X, we will follow these steps:

### Step 1: Calculate the moles of carbon dioxide (CO₂) produced.
At standard temperature and pressure (STP), 22,400 cm³ of CO₂ corresponds to 1 mole. We are given that 224 cm³ of CO₂ was collected.

\[ \text{Moles of CO₂} = \frac{224 \, \text{cm}^3}{22400 \, \text{cm}^3/\text{mol}} = 0.01 \, \text{mol} \]
