A hydrocarbon contains 10.5 g of carbon ...

A hydrocarbon contains `10.5 g` of carbon per gram of hydrogen. `1 L` of vapour of the hydrocarbon at `127^(@)C` and 1 atm pressure weighs `2.8 g`. Find the molecular formula of the hydrocarbon.

Text Solution

AI Generated Solution

To find the molecular formula of the hydrocarbon, we will follow these steps: ### Step 1: Determine the molecular weight of the hydrocarbon using the ideal gas law. The ideal gas law is given by the equation: \[ PV = nRT \] where: - \( P \) = pressure (in atm) - \( V \) = volume (in liters) ...
