Question

one mole of zinc atom weighs 65g . calculate the weight of one atom of zinc

Answer 1

1 mol of atoms = 6.022 × 10^23 atoms

Weight of one zinc atom = 65 g/mol × 1 mol/(6.022 × 10^23) = 10.8 × 10^-23 g

∴ Weight of one zinc atom is 10.8 × 10^-23 g

Answer 2

HI FRIEND ✋✋

1 MOLE OF ATOM = 6.022 × 10²³

WEIGHT OF 1 ZINC ATOM is :

[65g / 1 MOLE ] × [ 1 MOLE / 6.022 × 10²³]

= 65/(6.022 × 10²³)

= 10.793 × 10-²³

= 10.8 × 10^-23g [approx]
