Question

3. The weight of a single atom of oxygen is : (1) 1057 x 1023 g (2) 3.556 x 1023 g (3) 2.656 x 19-23 g (4) 4.538 x 10-23 g.​

Answer 1

Answer:

Explanation:

Weight of 1 molecule of oxygen (Atomic Mass) = 16

Number of atoms in 1 molecule of Oxygen is = 6.023×10 ^23 atoms

Weight of 1 atom of Oxygen - 16/ 6.023 * 10^23

2.656 * 10^-23
