The density of aluminum is 2.70g/cm3 and the density of chromium is 7.19g/cm3. If eual masses of aluminum and chromium are transferred to equal volumes of water in separate cylinders, which cylinder would have the greates volume change.
The easiest way to solve this problem is to assume some convenient mass, say 5 grams.
density = mass x volume and rearrange to
volume = mass/density.
volume Al = 5/2.70
volume Cr = 5/7.19
Draw conclusions from these data.
the Aluminum would have the greater change in volume because it is less dense
