Question

Calculate the no. of moles in 1×10^23 molecules CO2

Answer 1

given no. of molecule is 10^23 so
ac to formula
no of mole = given no. of molecule /avagadro no.
so, here
no of mole. = 10^23/6.022*10^23 = 0.16657

Answer 2

Hello friend !!!

First of all, 1 Mole consists of 6.023 × 10²³ particles (molecules, atoms, ions etc.)

Molar mass of CO2 = 12×1 + 16×2 =44g = 1mole of CO2
1 mole of CO2 contains 6.023 × 10²³ molecules

⇒6.023 × 10²³ = 1 mole
⇒1 × 10²³ = [1/6.023 ×10²³] × 1 × 10²³ = 1/6 = 0.167moles (approx.)
