The molar mass of Argon is 39.95g.
Therefore 1 mole of Argon is 39.95g
39.95 because that is the molar mass of Argon
39.948 is the atomic number.
7.66 X 10^5 millimols argon (1 mole argon/1000 mmol)(6.022 X 10^23/1 mole Ar) = 4.61 X 10^25 atoms of argon
Argon is 1% of the earth's atmosphere, making it much more abundant than any other noble gas.
From the Periodic Table, Argon has an atomic weight of 39.948. One mole of any element is equal to its atomic weight in grams. So 1 mole of Ar = 39.948g of Ar. Using that equality, you do the following calculation to find the number of moles of Ar in 22g of Ar: 22g Ar X 1mol Ar/39.948g Ar = 0.55mol Ar
39.95 because that is the molar mass of Argon
1 mole of argon weighs 39.948 g. So 7 moles will weigh 279.636 g
just divide the mass of sample by the mass of argon. OR: atomic mass of argon is 40 g/mol, so in a 40g sample of argon, there ought to be 1 mole atoms, or 6.02x10^23 atoms
39.948 is the atomic number.
7.66 X 10^5 millimols argon (1 mole argon/1000 mmol)(6.022 X 10^23/1 mole Ar) = 4.61 X 10^25 atoms of argon

Using that equality, you do the following calculation to find the number of moles of Ar in 22g of Ar: 22g Ar X 1mol Ar/39.948g Ar = 0.55mol Ar
Have: 607gAr Need: Moles of Argon From the periodic table we know that there are 39.948gAr per every 1 mole of Argon. 607g/39.948 = your answer.
6.02*10^26
The molar mass of a substance is measured in grams per mole written as gmol-1. It is worked out using the Mole formula by dividing mass in grams by the amount in moles.
it can be said that 1 mole oflithium is equal in mass to its molar mass wwhich is 6.94 g/mol
1 gram mole of Aluminium is about 27g.
