Question

A 32 g stick is thrown into 500 mL of liquid, and the new volume reads 540 mL. What is the liquid?


A)
Gasoline 0.7 g/cm3


B)
Alcohol 0.8 g/cm3


C)
Water 1 g/cm3


D)
Mercury 13.6 g/cm3

Answer 1

Answer:

A) Gasoline 0.7 g/cm³

Explanation:

Assuming the stick sinks, its density is:

ρ = (32 g) / (40 cm³)

ρ = 0.8 g/cm³

Therefore, the liquid density must be less then 0.8 g/cm³.

Only option A works.
