The student measured the mass of four of the potato sticks using an electronic balance.
(search at the google about an electronic balance)
the student left each potato stick in one of four different liquid for 5 hours.
$ distilled water
@0.1 mol per dm³ sodium chloride solution(salt)
@0.5 mol per dm³sodium chloride solution
@1.0 mol per dm³sodium chloride solution
after 5 hours they measured the mass again and calculated the change in mass
(i) predict which of the liquid would cause the largest decrease in mass of a potato stick.
(after you finish answer (i),i will write question (ii) )
warning ,dont write a link address from other website
if you did ,i will report you
dont ask at the answer place, ask at below this
its write ask for detail
