The molecule that has the lowest mass is 1.0 x 1023 molecules of O₂.

How to calculate mass?

The mass of a substance can be calculated by multiplying the number of moles by its molar mass.

However, based on the following molecules given, the number of moles can be calculated as follows:

  • 2.0 x 10²³ molecules of 03
  • 6.0 x 10²³ atoms of O
  • 1.0 x 10²³ molecules of O₂

  • 2.0 × 10²³ ÷ 6.02 × 10²³ = 0.33 moles
  • 6.0 × 10²³ ÷ 6.02 × 10²³ = 1 mole
  • 1.0 × 10²³ ÷ 6.02 × 10²³ = 0.17moles

  • mass of O3 = 0.33 × 48 = 15.84g
  • mass of O = 1 × 16 = 16g
  • mass of O2 = 0.17 × 32 = 5.44g

Therefore, the 1.0 x 10²³ molecules of O₂ of 02 has the lowest mass.
