Question

Convert 3.32x1025 atoms Xe to grams: (Answer) grams (3 SF)

Answer 1

Answer:

$m=7.24x10^3g$

Explanation:

Hello!

In this case, since 6.00x10²³ atoms of any element is related to one mole of atoms via the Avogadro's number, and the molar mass of xenon is 131.3 g/mol, we obtain the following mass in grams of xenon:

$m=3.32x10^{25}atoms*\frac{1mol}{6.022x10^{23}atoms}* \frac{131.3g}{1mol} \\\\m=7.24x10^3g$

Best regards!
