Chapter 7.6, Problem 10Q

Interpretation Introduction

Interpretation:

The mass percentage of given Neodymium (${\text{Nd}}_{\text{2}}{\text{Fe}}_{\text{14}}\text{B}$) compound has to be calculated.

Concept Introduction:

Mass percentage: This term used as a way of expressing a concentration (or) way of describing component in a mixture.

For example the calculation method the mass percentage (or) weight percent of solution you must divide the mass of the solute by the mass of the solution, both the solute and the solvent together and them multiply by 100 to change into percentage.

Let us consider the mass percentage formula.

    $\text{Mass}\text{Percent}\text{=}\frac{\text{grams}\text{of}\text{solute}}{\text{grams}\text{of}\text{solution}}\text{×}\text{100}$
