We need:

  • The atomic weight of Argon (Ar), which is 39.948. We will round to 39.9.
  • Avocado's Number, we'll use 6.02 * 1023

(40 g Ag) / (39.9 g/mol) * ( 6.02e23 atom/mol ) = 6.04 * 1023 atoms Ag

Alternatively, if you used 40 g as the atomic weight for Ar, you could just use Avocado's Number since (40 g / 40 g/mol = 1 mol )

The actual mass of an atom of argon is is 6.63x10-24g How many atoms are in a 40.0-g sample of argon?

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.


The mass of argon is 6.63 x 10-24g How many atoms are there in a 40.0 g sample argon?

First, calculate the number of moles in the 40.0 g sample of argon: 40.0 g / 39.948 g/mol = 1.00 mol. Then, use Avogadro's constant (6.022 x 10^23 atoms/mol) to find the number of atoms in 1.00 mol of argon, which is 6.022 x 10^23 atoms.

How many argon atoms are contained in 7.66x105 mmol of argon?

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.


How many argon atoms are contained in 7.66 and times 105 mol of argon?

There are approximately 4.61 x 10^26 argon atoms in 7.66 x 10^5 mol of argon. This calculation is based on Avogadro's number, which represents the number of atoms or molecules in one mole of a substance.
