# What is the mass of 2 moles of sulfur atoms?

Approx. $64 \cdot g$.
The mass of a mole of sulfur atoms is $32.06 \cdot g$. In $1$ $m o l$ of elemental sulfur, there are ${N}_{A} , \text{Avogadro's number}$ of sulfur atoms. You have a 2 mole quantity.
From where did I get that number $32.06 \cdot g \cdot m o {l}^{-} 1$. Will you have to remember it?
