Need Help with these 2. Will give Brainliest!! In a list of the densities of common materials, the one density that might not seem reasonable is .
Select one: a. 0.45 g/mL
b. 35 885 g/mL
c. 1.000 g/mL
d. 2.54 g/mL

Which of the following has the greatest density?
Select one: a.
a rock
b. oil
c. oxygen
d. ice

1. b

2. a

Explanation:

1. The density of an object represents the mass per unit volume of the object. A density of 0.45 g/mL means that 1 mL of the object weighs 0.45 g, 1.000 g/mL means 1 mL weighs 1 g, etc.

A density of 35,885 g/mL means that 1 mL of the object weighs 35,885 g. This is a ridiculously high amount of weight for an object with a volume of 1 mL and seems not reasonable. It is highly unlikely that such a substance exists in nature.

2. Considering the fact that only rock would sink in water of all the substances from a - d, it thus means that rock would have the greatest density. Oil, oxygen, and ice will all float on water, meaning that they are less dense than water.
