Question

The mass of oxygen atom would be
a) 3.01*10^12
b) 3.01*10^18
c) 2.656*10^-23
d) 4.536*10^-23​

Answer 1

Answer:

(C) 2.656*10^-23

Explanation:

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? Molar mass (in grams) is always equal to the atomic weight of the atom!
