Chapter 3, Problem 3.127P

Interpretation Introduction

Interpretation:

The N/P/K molar ratio of a 30/10/10 fertilizer is to be determined and expressed as x/y/1.0.

Concept introduction:

The number of moles is calculated by the formula as given below:

  $\text{Number of moles}=\frac{\text{given mass of sample}\left(\text{g}\right)}{\text{molar mass (g/mol)}}$        (1)

The formula to calculate mass is as follows:

  $\text{Mass of a given sample}\left(\text{g}\right)=\left(\text{molecular mass}\left(\text{g/mol}\right)\right)\left(\text{number of moles}\right)$        (2)
