# How many moles do 5.66 x 10^25 lithium ions, Li^+, equal?

Jan 31, 2017

Approx. $100 \cdot m o l$ $L {i}^{+}$
Well, $\text{one mole}$ represents $6.022 \times {10}^{23}$ items of stuff.
We have $\frac{5.66 \times {10}^{25} \cdot L {i}^{+}}{6.022 \times {10}^{23} \cdot m o {l}^{-} 1}$
$= 94.0 \cdot m o l$ $L {i}^{+}$ ions. What is the mass of this quantity?
