Chapter 3, Problem 3.96P

Interpretation Introduction

Interpretation: The N/P/L ratio of the 30/10/10 fertilizer in terms of number of moles 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:

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