Answer

$7.6\times 10^{-21}\ g\ Xe $

Work Step by Step

1. Use Avogadro's number and the molar mass of xenon as conversion factors in order to determine the mass of the xenon atoms. 2. $35\ atoms\ Xe\times\frac{1\ mol\ Xe}{6.022\times 10^{23}\ atoms\ Xe}\times\frac{131.3\ g \ Xe}{1\ mol\ Xe} = 7.6\times 10^{-21}\ g\ Xe $
