Density is a physical property that relates the mass of a substance to its volume. a. calculate the density, in g/ml , of a liquid that has a mass of 0.155 g and a volume of 0.000235 l. b. calculate the volume in milliliters of a 4.71-g sample of a solid with a density of 3.63 g/ml. c. calculate the mass of a 0.293-ml sample of a liquid with a density of 0.930 g/ml.

A) 0.660 g/ml

B) 1.297 ml

C) 0.272 g

Explanation:

Every substance, body or material has mass and volume, however the mass of different substances occupy different volumes.  This is where density appears as a  physical characteristic property of matter that establishes a relationship between the mass of a body or substance and the volume it occupies:

(1)

Knowing this, let's begin with the answers:

Here the mass is and th volume

Solving (1) with these values:

(2)

(3)

In this case the mass of a sample is and its density is .

Isolating from (1):

(4)

(5)

(5)

In this case the volume of a sample is and its density is .

Isolating from (1):

(6)

(7)

(8)

explanation:

the masses of the objects and the distance between them

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
