Question

Question 20
A graduated cylinder contains 100 mL of a liquid. The mass of the
graduated cylinder with the liquid is 145 grams. The mass of the
graduated cylinder when empty is 45 grams. The liquid is most likely
O Chloroform (Density = 1.492 g/mL)
Water (Density = 1 g/mL)
O Corn oil Density = 0.925 g/mL)
O Ethanol (Density = 0.789 g/mL)

Answer 1

Answer:

  (b)  Water

Explanation:

The density of the liquid is found by dividing its mass by its volume.

__

mass

The mass of the liquid is the difference in mass between the full and empty graduated cylinder:

  liquid mass = (145 g) -(45 g) = 100 g

volume

The cylinder is said to contain 100 mL of the liquid, so that is the volume of interest.

density

The ratio of mass to volume is the liquid's density:

  ρ = (100 g)/(100 mL) = 1 g/mL

This density identifies the most likely liquid as water.
