What is the mass of 0.2 mole of oxygen atoms?

Academic Chemistry NCERT Class 9

Mass of oxygen = 0.2 moles

Gram atomic mass of oxygen atom = 16g

Therefore, 16g of oxygen atoms = 1 mole of the oxygen atom

0.2 moles of oxygen atoms = 16 × 0.2g of oxygen atoms

Therefore, 0.2 moles of oxygen atoms weigh 3.2g.
