For these conversions, you need the atomic masses of the elements involved in grams. If it is just one element, then you use the Atomic Mass, but if its a compound, then use the molecular mass (added atomic masses). Take the number of moles and multiply it by the atomic (molecular) mass to get number of grams.

∙ 10y agoThe formula is number of moles = mass / molecular weight. Therefore, you have to multiply moles by molecular weight. The molecular weight can be found from the Periodic Table.

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 do you calculate mass of an unknown liquid in grams per mole?
you convert it to g/mole. Think of Mole as the word "dozen." Whenever you see the word "mole" just cross it out and put in the word "dozen". Do the problem like that, and then change all of your dozens to 6^1023. A dozen is 12. A bakers dozen is 13 and a mole is....whatever...some other big number. It doesnt matter. How do you calculate mass of a liquid in grams/dozen? You usese it's atomic weight which is in grams and then convert.
How many ions are there in 40 grams of calcium carbonate?
It depends on what it is reacting with.
If 16g of oxygen contains 1 mole of oxygen atoms calculate the mass of one atom of oxygen in grams?
1
What is the weight of 0.8834 mole oxygen gas?
Oxygen has a molar mass of 16 grams per mole 1 mole = 16 grams 0.8834 mole = x grams x=14.1344 grams
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 are in a mole of he?
4.003 grams
How do you calculate a mole of an atoms weight in grams?
you take the atomic mass of the atom (or molecule) and you have the mass in grams
How many grams are there in 0.61 mol of C6H12?
First calculate how many grams a mole of C6H12 weighs: Hydrogen is 1, and you have 12 hydrogens. Carbon is 6 and you have 6 carbons. So a mole weighs 1x12 + 6x6 = 48. Now multiply 48 x .61 and you have it. Final answer is in grams
How many grams of sodium are there in 10.0 grams of sodium sulfate?
Na2SO4 10.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(2 mole Na/1 mole Na2SO4)(22.99 grams/1 mole Na) = 3.24 grams of sodium -------------------------------
How you calculate the mass of 1.5 moles of oxygen molecule?
Multiply the molar mass value ( 32.0 grams per mole O2) by the number of moles (1.5 mole) to get its mass (48.0 grams for 1.5 mole O2)
