# Largest change in the water level [closed]

Which would produce the largest change in the $$\ce{H2O}$$ level when added to water in a $$\pu{25 mL}$$ graduated cylinder?

(A) $$\pu{10.0 g}$$ of $$\ce{Hg}$$ $$(d = \pu{13.6 g/mL})$$
(B) $$\pu{7.42 g}$$ of $$\ce{Al}$$ $$(d = \pu{2.70 g/mL})$$
(C) $$\pu{5.09 g}$$ of iron pyrite $$(d = \pu{4.9 g/mL})$$
(D) $$\pu{2.68 g}$$ of oak $$(d = \pu{0.72 g/mL})$$

I approached this question by dividing the mass by density to find the volume change. Thus, I got the answer (D), but the answer is (B).

Can anyone please explain this?
