# moles = mass / molar mass
= 1.23g / 83.80g/mol
=1.47x10^-2 moles

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.
If krypton is 30.00 how many grams are their?
If the molecular weight is 30 grams/mole, you need to know the number of moles to calculate the weight. If you have 1 mole, this will yield 30 grams of krypton.
How many grams is contained in 0.27 moles of calcium?
0,27 moles of calcium contain 10,82 g calcium.
How many moles of krypton do you have if you have 9.15 x 1024 atoms of krypton?
The answer is 15,2 moles.
