Hi. Are you lazy? Just find the mass of one mol and multiply by 3. (3.35*10^-23g per atom times 6.02*10^23 atoms equals 1 mol times 3 equals your answer.) Just do it!

this question is interesting because it is easy to do without this information
neon has a molecular weight of 20.179 grams/mol
so 3 moles has a mass of 60.537 grams
to see how your information compares you multiply
(3.35*10^-23)*(6.02*10^23)=20.2 which is the same as the published value (though less precise) and gives 60.5 when multiplied by 3
