C. There are the same number of molecules in one mole of carbon dioxide as there are in one mole of water.

Explanation:

The given problem will solve by using Avogadro number.

It is the number of atoms, ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 * 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 * 10²³ molecules of water

44 g of carbon dioxide = 1 mole = 6.022 * 10²³ molecules of carbon dioxide

So one mole of every substance will contain same number of molecules.
