0.75 " mol of "solid `X_(4)` and 2 " mol of "gaseous `O_(2)` are heated to react completely in sealed vessel to produce only one gaseous compound Y. After the compound is formed the vessel is brought to the initial temeprature, the pressure is found to half the inital pressure. Calculate the molecular formula of compound?

Explanation

To solve the problem, we need to determine the molecular formula of the compound Y formed from the reaction between solid \(X_4\) and gaseous \(O_2\). We will follow these steps:

### Step 1: Write the balanced chemical equation
Given that 0.75 moles of solid \(X_4\) react with 2 moles of \(O_2\) to produce one gaseous compound \(Y\), we can write the reaction as:
\[ X_4 + O_2 \rightarrow Y \]
