Calculate the number of moles in 1 × 1023 molecules of CO2
No.of moles = Given no.of particles ÷ Avogadro no: Given no.of particles = 10²³ ∴ No : of moles = 10²³ ÷ 6.022 × 10²³ = 1 / 6.022 = 0.16 moles.
Calculate the number of moles of CO2 presents in a sample containing 1.2044×1024 molecules of CO2.
