Question

1. the polypropylene cubes have a density of 0.946 grams per milliliter. identify the true statement(s)

select all that apply.
a. the cube sinks in 1 - butanol because 1 - butanols density is less than the cubes density.
b. the cube floats on water because the waters density is greater than the cubes density.
c. the cube sinks in 1 - butanol because 1 - butanols density is greater than the cubes density.
d. the cube floats on ethylene glycol because the cubes density is greater than ethylene glycols density.

Explanation:

• The density of polypropylene cube is \(0.946\ g/mL\).
• Density of 1 - butanol is approximately \(0.81\ g/mL\). Since \(0.946>0.81\), the cube sinks in 1 - butanol (so option A is correct and option C is wrong).
• Density of water is \(1\ g/mL\). Since \(0.946 < 1\), the cube floats on water (so option B is correct).
• Density of ethylene glycol is approximately \(1.11\ g/mL\). Since \(0.946<1.11\), the cube floats on ethylene glycol (so option D is wrong).

Answer:

B. The cube floats on water because the water's density is greater than the cube's density, A. The cube sinks in 1 - butanol because 1 - butanol's density is less than the cube's density.
