Answer 2

Answer:No. of molecules= 9.033 x 10^23

Explanation:No of moles=  m/M  =  48/32=  1.5 moles

                 No of molecules = no. of moles  x  NA

                                               =1.5  x   6.022  x  10^23

                                                 = 9.033  x   10^23 molecules
