QUESTION:
A gaseous hydrocarbon (containing C and H atoms) in a container of volume 20.2 L at 350 K and 6.63 atm reacts with an excess of oxygen to form 205.1 g of \(\mathrm{CO}_{2}\) and 168.0 g of \(\mathrm{H}_{2} \mathrm{O}\). What is the molecular formula of the hydrocarbon?
ANSWER:Step 1 of 3
Here we have to find out the molecular formula of the hydrocarbon.
Given:
Volume of the container = 20.2 L
Temperature = 350 K
Pressure = 6.63 atm
Mass of = 205.1 g
Mass of = 168.0 g
Molecular mass of = 44.01 g
Molecular mass of = 18.02 g
