If an alkane contains five carbon atoms, how many hydrogen atoms will it contain?

The alkane will have 12 hydrogen atoms.

Explanation:

Alkane is a type of hydrocarbon which is generally represented as

where, n = any whole number (1, 2, 3,4, ...)

These hydrocarbons have a single bond present between carbon and hydrogen.

So, for a alkane to have 5 carbon atoms, the value of 'n' will be equal to 5.

Hence, the alkane becomes

Therefore, the alkane having 5 carbon atoms will have 12 hydrogen atoms.
