# What is the mass of one mole of CO_2?

Apr 2, 2016

$44.009 g$

#### Explanation:

Finding the mass of a molecule is quite simple: add up the mass of the atoms that make it up. $C {O}_{2}$, for example, has one carbon and two oxygen.

Using mass numbers from the RSC periodic table, the total mass per mole is

$1 \cdot 12.011 g m o {l}^{-} 1 + 2 \cdot 15.999 g m o {l}^{-} 1 = 44.009 g m o {l}^{-} 1$

Because there is only one mole of $C {O}_{2}$,

$44.009 \frac{g}{m o l} \cdot m o l = 44.009 g$
