Question

How much mass would a mole of oxygen molecules contain? Recall that oxygen is diatomic. g/mol

Answer 1

32g/mol. The molar mass of an oxygen atom is ~15.999995, which is pretty much 16. Since oxygen is diatomic, you would multiply the molar mass of one atom by two (16 x 2) to get 32 g/mol

Answer 2

Answer: 32 g/mol

Step-by-step explanation:

According to Avogadro's law, 1 mole of every substance contains avogadro's number
`(6.023* 10^(23))` of particles and weighs equal to its molecular mass.

Diatomic molecule is a molecule formed by combination of two atoms of the same element. Example:
`O_2`

1 mole of oxygen
`O_2` molecule contains = 2 moles of oxygen atoms

1 mole of oxygen atom weigh= 16 g

2 moles of oxygen atoms weigh =
`(16)/(1)* 2=32 g`

Thus 1 mole of oxygen molecule weigh 32 g.
