Propane is one of the alkanes, which are usually memorized in basic chemistry classes, but the formula is C(n)H(2n+2), where n denotes the number of carbons. A carbon chain will have 2 hydrogens for each carbon, plus an additional one on each terminal carbon. For propane, n=3 as mentioned in the question (cyclic and non-cyclic will never change in number of carbons). Therefore 2n+2=8. The formula is C3H8.

You can practice this using any alkane. Butane is C4H10. Decane is C10H22.
