Question

If 6.02 into 10^21 molecules of co2 is removed from closed vessel
containing 0.1 moles Co2 then calculate remaining molecules
in container.

Answer 1

Answer:

No. of moles of CO2 gas = Volume of gas in Litres/22.4 = 0.1/22.4 = 1/224

No. of molecules of CO2 = No. of moles * Avogadro's number = 1/224 * 6.02* 10^23 = 0.026*10^23 = 2.6 * 10^21

Number of molecules of CO2 left = 2.6*10^21 - 10^21 = 10^21 (2.6-1) = 1.6*10^21

So, the number of CO2 molecules left is 1.6*10^21
