Question

Calculate the mass of a mole of carbon dioxide.

Answer 1

1. Mole is anything that contains the same amount of quantity which is equal to the number of atoms present in 12g of carbon 12 (C-12) which is 6.022 x 10²³.
2. The number of moles of an element is given by = Given mass/Atomic mass
3. The molar mass of ${\mathrm{CO}}_2$ is 44g.
4. The number of moles of ${\mathrm{CO}}_2$ is given by 1.
5. $\mathrm{Number}\mathrm{of}\mathrm{moles}=\frac{\mathrm{Given}\mathrm{Mass}}{\mathrm{Atomic}\mathrm{Mass}}$
6. $1=\frac{\mathrm{Mass}}{44}$
7. $\mathrm{Mass}=44\mathrm{g}$
8. The mass of 1 mole of the substance is the molar mass that is 44g in case of ${\mathrm{CO}}_2$, we can calculate in such a manner also.

Therefore, the mass of 1 mole of ${\mathrm{CO}}_2$ is 44g.
