The molar mass of Argon is 39.95g. Therefore 1 mole of Argon is 39.95g
39.948 is the atomic number.
39.95 because that is the molar mass of Argon
Argon is 1% of the earth's atmosphere, making it much more abundant than any other noble gas.

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
1 mole of argon weighs 39.948 g. So 7 moles will weigh 279.636 g

The atomic mass of argon is 4 g. So one atom of argon will weigh 0.004 kg
Gold, as it has the higher molar mass.
Since Argon has a relative atomic mass of 39.95, and mols = grams / RAM, one could calculate 39.95 / (6.02*10^23) = 6.63 * 10^-23 grams [0.00000000000000000000006634g] for a single argon atom, where 6.022 * 10^23 is roughly Avogadro's constant (the count of atoms in a mole). IF my math is correct.
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
32 grams, you can find the mass of one mole of any element by looking at its atomic mass eg chlorine has Atomic mass of 35.5 so the mass of one mole of chlorine is 35.5 grams.
