How many molecules are in 0.26 mol of CO_2?

Jul 8, 2018

Well, how many carbon dioxide molecules are present in ONE MOLE of $C {O}_{2}$?

Explanation:

I make it $6.022 \times {10}^{23} \cdot \text{individual molecules} \cdot m o {l}^{-} 1$

And so we take the product...

$6.022 \times {10}^{23} \cdot \text{individual molecules} \cdot m o {l}^{-} 1 \times 0.26 \cdot m o l$

$\equiv 1.57 \times {10}^{23}$ $\text{individual molecules}$. How many ATOMS in this quantity, and what is the associated mass?
