Question

A cylinder has a mass of 14.98g and a volume of 2.10 ml. what is the cylinder's density?

Answer 1

7.133 g/cm^3

Step-by-step explanation:

Density = mass ÷ volume

Given,

mass = 14.98 g

Volume = 2.10 ml = 2.10cm^3 [because 1 ml= 1cm^3]

density = 14.98÷ 2.10

density = 7.133 g/cm^3

Answer 2

`\boxed {\tt d\approx7.13 \ g/mL}`

Step-by-step explanation:

The density of an object can be found by dividing the mass by the volume.

`d=(m)/(v)`

The mass of the cylinder is 14.98 grams.

The volume of the cylinder is 2.10 milliliters.

`m=14.98 \ g\\v= 2.10 \ mL`

Substitute the values into the formula.

`d=(14.98 \ g)/(2.10 \ mL)`

Divide.

`d=7.13333333 \ g/mL`

Round to the nearest hundredth. The 3 in the thousandth place tells us to leave the 3 in the hundredth place.

`d\approx 7.13 \ g/mL`

The density of the cylinder is about 7.13 grams per milliliter.
