Question

Determine the mass of an object that, when places in a 25-mL Graduated cylinder containing 14 mL of water, causes the level of the water to rise to 19 mL. The object has a density of 3.2 g/mL.

How do you set up the equation?

Answer 1

Mass = Density x Volume
Mass = 3.2g/mL x 5 mL
Mass = 16g

Answer 2

Answer: The mass of the object is 16 g.

Step-by-step explanation:

Density is defined as the mass contained per unit volume.

`Density=(mass)/(Volume)`

Given : Mass of object = ?

Density of the object =
`3.2g/ml`

Volume of the object = Volume of water displaced =(19-14) ml = 5 ml

Putting in the values we get:

`3.2g/ml=(Mass)/(5ml)`

`Mass=16g`

Thus the mass of the object is 16 g.
