Chapter 3, Problem 3.97P

Interpretation Introduction

Interpretation: The mass percents of ammonium sulfate, ammonium hydrogen phosphate and potassium chloride used to prepare 10/10/10 plant fertilizer needs to be determined.

Concept Introduction: The number of moles can be calculated as follows:

  $n=\frac{m}{M}$

Here, m is mass and M is molar mass.

Also, the mass percent of the component of mixture can be calculated as follows:

  $\%m_A=\frac{m_A}{m_{\text{compound}}}\times 100\%$
