What is the mass of 7.3 moles of C_3H_8?

Mar 3, 2016

Approx. $320$ $g$.

Explanation:

Propane has a molecular mass of $44.10$ $g \cdot m o {l}^{-} 1$.

So, all I have to do is multiply this quantity by the molar quantity:

$7.3 \cdot \cancel{m o l} \times 44.10 \cdot g \cdot \cancel{m o {l}^{-} 1}$ $=$ ??g

How many carbon atoms are present in this mass?
