#~~ 4.06 * 10^23 "atoms Rn"#

Explanation:

The number of atoms in a mole of a element or compound is expressed by Avogadro's constant #~~ 6.022 * 10^23#. Using this value, we can compute for the number of Rn atoms...

#(0.675 "mol Rn") * (6.022 * 10^23 "atoms Rn")/(1 "mol Rn")#
#~~ 4.06485 * 10^23 "atoms Rn"#
#~~ 4.06 * 10^23 "atoms Rn"#
