(Symbol Ar) / Atomic weight 39.948
The atomic mass of argon is approximately 39.95 atomic mass units.
The atomic mass of argon is approximately 39.95 grams per mole.
Argon is a non metal element. Mass number of it is 40.
Argon is a non metal element. Atomic mass of it is 39.94.
The relative atomic mass is 39.95
(Symbol Ar) / Atomic weight 39.948
The mass no of argon is 39.948
The molar mass of Argon is 39.95g. Therefore 1 mole of Argon is 39.95g
The atomic mass of argon is 4 g. So one atom of argon will weigh 0.004 kg
The mass number of an atom of argon is 40. This number represents the total number of protons and neutrons in the nucleus of the argon atom.
Argon is a non metal element. Atomic mass of it is 39.94.
Mass of 1mole of Argon is 39.95g. So, The mass of 7 moles of Argon is 39.95x7= 279.65g.
The atomic mass of argon is approximately 39.95 atomic mass units.
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.
The mass number of Argon is 39.948 so it is 119.98/39.948=3.0034 moles of Argon in 119.98 g of Argon or approximately 3 moles of Argon is in 119.98 g this gas.
Argon is a non metal element. Mass number of it is 40.
