Question

Mass of one atom of oxygen? ​

Answer 1

Answer:

There is a unique relationship between molar mass and

atomic weight:

Oxygen’s atomic weight is 16.00 amu.

1 mole of oxygen is 6.02 x 1023 atoms of oxygen

1 amu = 1.661 x 10-24g

What is the molar mass (g/mole) of oxygen?

16.00 amu/oxygen atom x 1.661 x 10-24g/amu

= 2.657 x 10-24 g/atom x 6.02 x 1023 atoms/mole

=16.00 g/mole

Molar mass (in grams) is always equal to the atomic weight

of the atom
