Solutions

Expert Solution

45.67 pg/g  

pg = 10^15 g

45.67 pg/g =45.67*10^15g/g

                   = 45.67*10^15g/10^-3kg

                  = 45.67*10^18g/kg                           [ 1g/kg = 1000ppm]

                = 45.67*10^18*1000ppm

               = 45.67*10^21ppm

                = 4.567*10^22 ppm >>>>>answer
