# How many atoms of tin are there in 3.50 moles of tin?

How many eggses are there in $3$ $\frac{1}{2}$ dozen eggses........?
And in $3.50$ moles of tin, we have simply upped the ante, and now our $\text{dozen"-=N_A="Avogadro's number} = 6.022 \times {10}^{23} \cdot m o {l}^{-} 1$.
So we calculate the product, $3.50 \cdot m o l \times 6.022 \times {10}^{23} \cdot m o {l}^{-} 1 =$ ??
