How many molecules of oxygen gas (02) are in 8.00 grams of

oxygen?

1.51*10²³

Explanation:

Convert to moles first

moles=mass/molar mass

moles=8.00/32 (molar mass of oxygen is multiplied by 2 since it is diatomic)

moles=1/4

multiply moles with Avogadro's constant

1/4*6.02*10²³

1.505*10²³

1.51*10²³ molecules of O₂ are in 8.00 grams of Oxygen.
