How many atoms are in 0.0077 mol C?
There are approximately 4.65 x 10^22 atoms in 0.0077 mol of carbon.
How many atoms are in 22 grams of argon?
There are approximately 6.023 x 10^23 atoms in 1 mole of any element, including argon. The molar mass of argon is approximately 40 grams/mol, so 22 grams of argon would contain about (6.023 x 10^23 atoms/mol) * (22 grams / 40 grams/mol) = 3.34 x 10^23 atoms of argon.
How many atoms in 10 grams of gold?
There are about 2.56 x 10^22 atoms in 10 grams of gold. This calculation is based on the atomic mass of gold (197 g/mol) and Avogadro's number (6.022 x 10^23 atoms/mol).
What is the mass in grams of 3.40x10 22 atoms He?
To find the mass of 3.40x10^22 helium atoms, you need to know the molar mass of helium, which is 4.0026 g/mol. So, the mass of 3.40x10^22 helium atoms would be 3.40x10^22 atoms * (4.0026 g/mol/6.022x10^23 atoms/mol) ≈ 2.27 grams.
How many atoms are in 1.6 g C?
There are approximately 1.34 x 10^22 carbon atoms in 1.6 g of carbon. This calculation is based on the molar mass of carbon (12 g/mol) and Avogadro's number (6.022 x 10^23 atoms/mol). To find the number of atoms, divide the mass of the sample by the molar mass of carbon, and then multiply by Avogadro's number.

How many atoms are in 0.0602 mol K?
0.0602 mole K x 6.02x10^23 atoms/mole = 3.62x10^22 atoms
A small pin contains 0.0178 mol of iron how many atoms of iron are in the pin?
To calculate the number of iron atoms in 0.0178 mol of iron, you can use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Number of iron atoms = 0.0178 mol x 6.022 x 10^23 atoms/mol = 1.07 x 10^22 atoms.

How many atoms of phosphorus are in a 0.577 g sample?
1.12 x 10^22 atoms PFirst determine the number of moles in the 0.577 g sample of phosphorus, determine the number of moles in the sample. Then multiply the moles by 6.022x10^23 atoms/mol.0.577 g P x (1 mol P/30.974 g P) x (6.022x10^23 atoms P/1 mol P) = 1.12 x 10^22 atoms P
How many atoms of He gas are found in 0.268 g. the molar mass of He. the moles of He. the number of atoms of He gas .?
To find the number of atoms of He gas in 0.268 g, first calculate the moles of He using the molar mass of He (4.0026 g/mol). 0.268 g / 4.0026 g/mol ≈ 0.067 mol of He. Then, use Avogadro's number (6.022 x 10^23) to find the number of atoms: 0.067 mol x 6.022 x 10^23 atoms/mol ≈ 4.03 x 10^22 atoms of He gas in 0.268 g.
