Recall that liquid sodium reacts with chlorine gas to produce sodium chloride. You want to produce 581 g of sodium chloride. How many grams of sodium are needed?

Mar 4, 2016

$N a \left(g\right) + \frac{1}{2} C {l}_{2} \left(g\right) \rightarrow N a C l \left(s\right)$. Approx. $230$ $g$ sodium metal are required.
$\text{Moles of sodium chloride}$
$\frac{581 \cdot \cancel{g}}{58.44 \cdot \cancel{g} \cdot m o {l}^{-} 1}$ $=$ $\text{approx. } 10 \cdot m o l$
Thus $10$ $m o l$ sodium metal are required.
