Question

The density of titanium is 4.5 ​ g/cm3 ​. A titanium ring has a volume of 0.4 cm³.

What is the mass of the titanium ring?

Enter your answer as a decimal in the box.

Answer 1

Density = mass / volume
4.5 = mass / .4
mass = 4.5*.4
mass = 1.8 grams

Answer 2

The mass of the titanium ring is 1.8 grams.

Explanation:

Given : The density of titanium is 4.5 ​ g/cm³ ​. A titanium ring has a volume of 0.4 cm³.

We have to find the mass of the titanium ring.

Using formula for density

`Density=(Mass)/(Volume)`

Rearranging for mass, we have

Multiply both side by Volume, We have,

`Mass=Density* Volume`

Given: Density = 4.5 g /cm³ and Volume = 0.4 cm³

Thus,
`Mass=4.5* 0.4`

Smplify, we have,

`Mass=1.8`grams

Thus, The mass of the titanium ring is 1.8 grams.
