What do you mean? If you clarify, I'll answer in the comments.
The number of moles of carbon dioxide is 0.05 mol.
A molecule of CO2 contains one carbon atom and two oxygen atoms. One mole of CO2 contains one mole of carbon atoms and two moles of oxygen atoms. The mass of one atomic mole of an element equals the atomic mass in grams, and the molecular mass of an element or compound equals the sum of the atomic masses of each type of its constituent atoms.
Therefore, the mass of one mole of a molecule of an element or compound equals its molecular weight in grams. The number of grams in moles depends on the substance you have. To calculate it, find the atomic or molecular mass of the substance and multiply it by the number of moles.
