To calculate the mass of a given number of atoms of an element, you need to know the molar mass of that element. The molar mass represents the mass of one mole of atoms or molecules of a substance, and it is expressed in grams per mole (g/mol).
The molar mass of oxygen (O) is approximately 16.00 g/mol.
Avogadro's number, 6.022 x 10^23, represents the number of atoms or molecules in one mole of a substance.
To find the mass of 6.022 x 10^23 atoms of oxygen, you can use the following calculation:
Mass = (Number of atoms) x (Molar mass)
Mass = (6.022 x 10^23 atoms) x (16.00 g/mol)
Mass = 9.6352 x 10^24 g
Therefore, the mass of 6.022 x 10^23 atoms of oxygen is approximately 9.6352 x 10^24 grams.
