The number of atoms present in 16g of oxygen is(1) 6.02 x 10i1s(3) 3.01 x 10115(2) 3.01 x 10(4) 6,02 x 101

Answer»

16 g i equal to 0.5 mole of oxygen molecule. we know in one molecule of oxygen there are 2 atom. Hence in 0.5 mole of oxygen molecule, there are 0.5 * 2 mole of atom of oxygen. that is 1 mole of oxygen atom.

Number of particle in one mole = 6.022 * 10^233.

Thu number of atom in 16 g of oxygen gas = 6.022*10^23
