C3H8

The ratio between carbon atoms and hydrogen atoms in all Alkanes can be easily determined using the following formula:

H = 2(C+1)

where C is the number of Carbon atoms and H is the number of Hydrogen atoms.

You can determine the number of Carbon atoms simply from the prefix, which in this case is PRO, so it means 3 Carbon atoms.

H = 2(3+1) = 2 x 4 = 8
