## A 28 .4-cm 3 sample of titanium has a mass of 127 .8 g . Calculate the density of titanium in g/cm 3 .

Interpretation Introduction

Interpretation:

The density of titanium in (g/cm3) is to be calculated.

Concept Introduction:

Density is defined as the ratio of mass and volume, or mass per unit volume.

The expression is as follows:

density(d) = mass(m)volume(V)

Calculation of density(d) of a substance requires the division of its mass(m) by its volume(V). Therefore, the most commonly used units are:

 Gram per cubic meters (g/cm3)

 Gram per milliliter (g/mL)

### Explanation of Solution

Given information: Mass of sample of titanium =127.8 g

Volume of sample of titanium =28.4 cm3

The density of titanium sample is calculated by the following expression:

d= mV

Substitute the values of mass and volume in the above expression
