Chapter 4, Problem 88A

Interpretation Introduction

Interpretation : The mass of platinum is to be calculated.

Concept Introduction : Mass is a measure used to quantify an object in comparison to that standard mass of 1 kilogram. The connectivity between density and volume is mass. The formula of mass is given as:

  $\text{Mass}\text{=}\text{Density×Volume}$

Answer to Problem 88A

The mass of platinum is $99.5\text{g}$ .

Explanation of Solution

Mass is a measure used to quantify an object in comparison to that standard mass of 1 kilogram. The connectivity between density and volume is mass. The formula of mass is given as:

  $\text{Mass}\text{=}\text{Density×Volume}$

The given Volume of platinum is $4.42{\text{cm}}^3$ .

The given density of platinum is $22.5{\text{g/cm}}^3$ .

To calculate the mass of platinum, substitute the values in the above equation.

  $\begin{array}{c}\text{Mass}\text{=}\text{Density×Volume}\\ =22.5\text{g /}\cancel{{\text{cm}}^3}\times 4.42\cancel{{\text{cm}}^3}\\ =99.5\text{g}\end{array}$

The mass of platinum is $99.5\text{g}$ .
