Answer

$6.02\times10^{23}\times3.35\times10^{-23}\times2$ $40.334$ $4.0334\times10^{1}$

Work Step by Step

We are given the number of atoms in a mole(which you may know to be 6.02x10^23) and the mass of a single neon atom. Then multiply these 2 numbers to find the mass of a mole of neon atoms. Finally multiply by 2 to determine the molar mass of 2 neon atoms. The final step is just to simplify the answer in scientific notation.
