# Chemistry density question watch

Announcements
1. Which of the following objects will sink when dropped into a bucket of water? Given: density of water = 1.00 g/cm3)
A. a cube of aluminum (density = 2.702 g/cm3)
B. a diamond (density = 3.51 g/cm3)
C. a chunk of dry ice (density = 1.56 g/cm3)
D. a chunk of sodium (density = 0.91 g/cm3)
E. a sphere of magnesium (density = 1.74 g/cm3)

the answer is D, wouldn't all of them suppose to sink except for D?
2. Your conclusion is correct - things with a density greater than 1.00 g/cm3 will sink in water. There must be an error somewhere.
