# What molar quantity is represented by 1.084xx10^25 oxygen molecules?

Sep 13, 2017

Well, 18 moles......with respect to dioxygen...

#### Explanation:

I could ask the same question question using $\text{dozens}$ in place of $\text{moles}$. I have $36$ ${C}_{6} {H}_{12} {O}_{6}$ molecules or $\text{3 dozen}$ sugar molecules.....clearly I have

....$\left(6 \times 36 \cdot {\text{oxygen atoms")/(12*"oxygen atoms"*"dozen}}^{-} 1\right)$

$= 18 \cdot \text{dozen"*"oxygen atoms}$

And in the question, we replace $\text{dozen}$ with $\text{mole}$, where $1 \cdot m o l \equiv 6.022 \times {10}^{23}$ individual items.....

What is the mass of this quantity of oxygen atoms?
