Question

A 210 gram piece of metal has a volume of 81 cm3. What is the density of this metal?

Question 15 options:

129 g/cm3


2.59 g/cm3


0.39 g/cm3


17,010 g/cm3


291 g/cm3

Answer 1

The answer is

`2.59 \: \: g / {cm}^(3)`

Step-by-step explanation:

The density of an object can be found by using the formula

`Density( \rho) = (mass)/(volume)`

From the question

mass of metal = 210 g

volume = 81 cm³

Substitute the values into the above formula and solve for the density

That's

`Density = (210)/(81) \\ = (70)/(27)`

= 2.592592

We have the final answer as

Density = 2.59 g/cm³

Hope this helps you
