# How many grams are in 4.40 mol of sodium chloride?

Jun 26, 2016

Approx. $250 \cdot g$ of salt.
$4.40 \cdot \cancel{m o l} \times \left(22.99 + 35.45\right) \cdot g \cdot \cancel{m o {l}^{-} 1}$ $=$ ??*g
From where did $\left(22.99 + 35.45\right)$ come? What is the mass of an equivalent molar quantity of $L i F$? Should it have greater or less mass than the above; why?
