Answer:
1 mole of O₂ has more mass compared to 1 mole of Na
Explanation:
1 mole oxygen atom and 1 mole of Na atom has the same number of particles.
A mole of any substance has the Avogadro number of particles which is
6.02 x 10²³
Mass of a substance = number of moles x molar mass
Molar mass of O₂ = 2(16) = 32g/mol
Molar mass of Na = 23g/mol
Mass of O₂ = 1 x 32 = 32g
Mass of Na = 1 x 23 = 23g
So, 1 mole of O₂ has more mass compared to 1 mole of Na
