A hydrocarbon is an organic compound that contains carbon and hydrogen atoms.
The simplest hydrocarbons are called alkanes, where the molecule has only single bonds connecting carbons and hydrogens together.
An alkene is a hydrocarbon with one or more carbon to carbon double bonds.
An alkyne is a hydrocarbon with one or more carbon to carbon triple bonds.

In a spacecraft, the carbon dioxide exhaled by astronauts can be removed by its reaction with lithium hydroxide, LiOH, according to the following chemical equation.
CO2(g) + 2LiOH(s) = Li2CO3(s) + H2O(l)
If 20.0 moles of CO2 is exhaled, the average amount exhaled by a person each day, how many grams of LiOH(s) is required?
