How many atoms are in 8O2?

Answer 1

we have to calculate number of moles in 8gram of oxygen by the equation given mass/molar mass.then we would get that 0.25moles are in 8 g of oxygen molecules.then multiply this to avagadro number .then we could get the number of particles.

Answer 2

You'll need some memorized numbers:

1 mole = 6.022x 1023 particles.

Oxygen gas = 2 atoms (because it always comes as a diatomic molecule)

Multiply them all out, and you'll get your answer. Remember significant figures.

Answer 3

8 molecules of oxygen contain 16 atoms.

Answer 4

There are 16 atoms in 8O2. Since each molecule of O2 contains 2 oxygen atoms, multiplying 8 by 2 gives you a total of 16 atoms.

Answer 5

0.25
