The mass of 1 mole of an element is its atomic weight on the Periodic Table in grams.
1g = 1000mg
The mass of 1 mole of Kr = 83.80g Kr
Convert mg Kr to g Kr.
398mg Kr x (1g/1000mg) = 0.398g Kr
Convert g Kr to mol Kr.
0.398g Kr x (1mol Kr/83.80g Kr) = 4.75x10-3mol Kr

How many moles are in 1.7 times 10 to the 25th power atoms of krypton?
1 mole Kr = 6.022 x 1023 atoms 1.7 x 1025 Kr atoms x (1 mole Kr)/(6.022 x 1023 Kr atoms) = 28 moles Kr (rounded to two sig figs)
How do you convert 1.29 mol Kr to a number of atoms?
Just multiply the moles of Kr by Avogadro's number. Formal set up.1.29 moles Kr (6.022 X 1023/1 mole Kr)= 7.77 X 1023 atoms of krypton====================
How many grams are contained in 4.56 moles of krypton Kr?
4.56 moles Kr x 83.798 g/mole = 382.119 grams = 382 grams (to 3 significant figures)NOTE: You should not use more than 3 significant figures since 4.56 moles limits the precision. Thus the answers of 381.66g and 382.1188 g are incorrect.
What is the mass of 9.46E plus 23 atoms of krypton?
I think you do not need the " plus. " 9.46 X 10^23 atoms Krypton (1 mole Kr/6.022 X 10^23)(83.80 grams/1 mole Kr) = 132 grams of Krypton ---------------------------------
