To find the number of atoms in 88g of oxygen, we first need to determine the molar mass of oxygen (O).
The molar mass of oxygen is approximately 16g/mol.
Next, we can calculate the number of moles of oxygen in 88g using the formula:
Number of moles = Mass (g) / Molar mass
Number of moles = 88g / 16g/mol
Number of moles = 5.5 mol
Finally, we can calculate the number of atoms in 5.5 moles of oxygen using Avogadro's number, which is 6.022 x 10^23 atoms/mol:
Number of atoms = Number of moles x Avogadro's number
Number of atoms = 5.5 mol x 6.022 x 10^23 atoms/mol
Number of atoms = 3.3121 x 10^24 atoms
Therefore, there are approximately 3.3121 x 10^24 atoms in 88g of oxygen.
The molar mass of oxygen is approximately 16g/mol.
