Question

the number of molecules in 22.4cm3​

Answer 1

Answer:

For no. of molecules = moles x NA

now the volume is given

..

22.4cm3 means 22.4ml

moles = Volume / 22.4

moles = volume / 22400(for ml)

so

moles =22.4/22400

= 0.001

no. of molecules = 0.001 x NA

= 0.001 x 6.022x10^23

= 0.006022 x 10^23 molecules
