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
1,600
63.8g
atoms are made of molecules and that is why they are related !

The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / molTo convert atoms to moles:moles P= 3.78E+24 atoms P1 mol P = 6.28 mol P6.02 x 1023 atoms PMultiply by moles per atom. Atoms cancel out.
Divide 40g by the mass of one atom to find the number of argon atoms.
1.7x10^-18
2.3 × 1024 atoms of Ar
2.3 × 1024 atoms of Ar
1,67.1024 argon atoms is equal to 2,773 moles.
Approx 1.5*10^23 atoms.
Approx 0.223 moles.
There are 18 electrons and protons each in argon atoms.
There are 18 electrons and protons each in argon atoms.
Approx 5.34*10^23 atoms.
The answer is 3.32*10^23 atoms
Approx 3.32*10^23 atoms.
