# What is the unit used to describe molar mass?

$\text{Grams, pounds, kilograms per mole?}$
A mole is a numerical unit....specifically it represents the number of carbon atoms in a $12.00 \cdot g$ mass of ""^12C, and this number is ${N}_{\text{A"-="Avogadro's constant}} \equiv 6.022140857 \left(74\right) \times {10}^{23} \cdot m o {l}^{-} 1$. And the Periodic Table conveniently gives the mass associated with ${N}_{A}$ atoms of each element....
