# If an average atom of sulfur weighs 32.07 many sulfur atoms are contained in sample with mass 8274 amu? What is the mass of 5.213 x 10^24 sulfur atoms?

258 atoms, $1.67 x {10}^{26}$ amu
$\left(\frac{1}{32.07}\right)$ (atom/amu) * (8274) amu = 258 atoms#
$\left(32.07\right)$ (amu/atom) * $5.213 x {10}^{24}$ atoms = $1.67 x {10}^{26}$ amu
