Question

if 16g of oxygen contain 1 mole of oxygen calculate the mass of one atom of oxygen​

Answer 1

Answer:

Ans. 1 Mole of Oxygen = 6.022 × 1023 atoms

=> 6.022 ×10 23 atoms have weight = 16g

=> weight of 1 atom  = 166.022 ×1023

=> 2.66 ×10-23 g

Answer 2

Mass of 1 mole of oxygen = 16g

We know that 1 mole of oxygen contains 6.022 × 1023 oxygen atoms.

Mass of 6.022 × 1023 oxygen atoms = 16g

Mass of 1 oxygen atom = 16/6.022 × 1023

Hence, 1 atom of oxygen molecule weighs 2.65 × 10-23 grams.
