Answer:
D
Explanation:
We already know oxygen's mass is 15.99 amu, and the mass of a mole is 6.02 * 10^23, so just multiply the two together for 15.99 * (6.02 * 10^23) g.
15.99 x (6.02x[tex]10^{23}[/tex])g mass does 1 mol of O2 gas have. Hence, option D is correct.
A mole is defined as 6.02214076 × [tex]10^{23}[/tex]of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
