THE FULL QUESTION IS IT IS COOLED FROM 80C TO 30C YOU PEOPLE JUST PUT COOLED PLEASE CHECK AND CORRECT IT THE DIAGRAM IS COORECT SO WHEN YOU TRACE THE 80C IT GIVE 8 MOL/DM3 AND WHEN YOU TRACE THE 30C IT GIVES 6 MOL/DM3 SUBTACT THEM IT GIVES 2 MOL/DM3 AND WE KNOW MOLE =MASS/MOLARMASS SO MASS =MOLARMASS X MOLE WHICH IS 74.5 X 2 WHICH =149g
