Acork has a mass of 3 grams and a volume of 16 cms calculate the density

hey mate here is ur answer

solution

mass{m}=3 gram

             =3/1000

volume{v}=16cm

                =16/100

density=m/v

           =3/1000÷16/100

           =3/160

            =0.01875kg/m3

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
