Question

Calculate the no. of molecules present in 56ml of CO2 at STP
Step by step answer required​

Answer 1

Number of molecules = Avogadro's number x Number of Moles

Volume of 1 mole of a gas at STP is 22.4l

Which means there are 56/22400 moles CO2 = 1/400 moles

Number of molecules = (6.023x10^23)x(1/400)

The answer would be 1.506 x 10^21

Answer 2

answer is 4.518 x 10 power 20

hope it helps....
