The density of ice is 0.92 g/cm³; and the density of seawater is 1.03 g/cm³. A large iceberg floats in Arctic waters. What fraction of the volume of the iceberg is exposed? A)0.080 % B)11 % C)89 % D)92 % E)99 %

Question

Quizplus · Accepted Answer

When an object floats, it displaces its own weight of fluid. Therefore, the fraction of the volume of the iceberg that is exposed is equal to the ratio of the density of ice to the density of seawater: 
(0.92 g/cm³) / (1.03 g/cm³) = 0.8932 ≈ 89% 
Thus, approximately 89% of the volume of the iceberg is exposed above the sea level.

The Density of Ice Is 0
