Approx 5.34*10^23 atoms.
Argon is an element and all the atoms in argon are argon atoms.
To find the number of argon atoms in a 40.0-g sample, you first need to calculate the number of moles of argon in the sample using the molar mass of argon (39.95 g/mol). Then, you can use Avogadro's number (6.022x10^23 atoms/mol) to determine the number of atoms in that many moles of argon.
A mole of argon includes Avogadro's Number of atoms of argon. Therefore, the answer is (3.0 X 1024)/(6.022 X 1023) or 5.0 moles, to the justified number of significant digits.
There are 18 electrons and protons each in argon atoms.
To find the number of argon atoms, we first need to convert the amount from millimoles to moles by dividing by 1000. Next, we use Avogadro's number, which is 6.022 x 10^23 atoms/mol, to calculate the number of atoms in 7.66 x 10^2 moles of argon. The result is approximately 4.61 x 10^26 argon atoms.
The answer is 38,174.10ex.23 atoms
