An iceberg has a volume of 7655 cubic feet. What is the mass of the ice in Mg? Density of water = 1.000 g/mL. 1 kg = 2.205 lb.

Question

An iceberg has a volume of 7655 cubic feet.  What is the mass of the ice in Mg?  Density of water = 1.000 g/mL.  1 kg = 2.205 lb.

Throwing a bit of a curve ball here, as the density of water is significantly different than the density of ice, as anyone who has ever frozen water in a closed container knows!

whpalmer4 · Answer

Convert the volume from cubic feet to cubic centimeters.  Multiply by the density of water (or better yet, ice) to get grams.  Convert that to Mg.

Wolfram|Alpha gives a value of 0.9169 g/mL for the density of ice.  That means your block of ice occupies 1.000/0.9169 = 1.091 or 9.1% more space than it does melted!
