To find the molecular formula of the hydrocarbon based on the given data, we can follow these steps: ### Step 1: Calculate the molar mass of the hydrocarbon using the given volume and mass. We know that 1 mole of gas at Standard Temperature and Pressure (S.T.P) occupies 22.4 liters (or 22400 mL). Given: - Volume of gas = 132 mL - Mass of gas = 0.342 g ...
