How many moles are in 3.0x1024 atoms of argon?
To find the number of moles in 3.0x10^24 atoms of argon, divide the given number of atoms by Avogadro's number (6.022x10^23 atoms/mol). So, 3.0x10^24 atoms of argon is equal to 5 moles of argon.
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.
How many moles of argon gas contain 7.52 x 10 to the 23 power?
0.125 moles of argon gas contain 7.52 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 (Ar) atoms are there in 1.5 x 102 g if argon?
To find the number of argon atoms in 1.5x10^2g of argon, we first need to determine the molar mass of argon. The molar mass of argon is approximately 39.95 g/mol. Next, we convert the given mass to moles by dividing by the molar mass. Finally, we use Avogadro's number (6.022x10^23) to convert moles to atoms. The number of argon atoms in 1.5x10^2g of argon would be approximately (1.5x10^2g / 39.95g/mol) x 6.022x10^23 atoms.
