# What is the mass of oxygen in a 233.0*g mass of carbon dioxide?

Apr 8, 2017

$\text{Mass of oxygen} \equiv 170 \cdot g$.

#### Explanation:

We calculate the molar quantity of carbon dioxide is........

$\frac{233 \cdot g}{44.0 \cdot g \cdot m o {l}^{-} 1} = 5.30 \cdot m o l$

Now, clearly, if there are $5.30 \cdot m o l$ $C {O}_{2}$, there are $10.6 \cdot m o l$ $\text{oxygen atoms}$. Do you agree?

And thus mass of oxygen $\equiv$ 10.6*molxx16.0*g*mol^-1=??g.
