Chapter 4, Problem 4.86P

Interpretation Introduction

Interpretation: The mass of the magnesium that can be obtained needs to be determined using the given information.

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:

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

Also, density can be calculated as follows:

  $d=\frac{m}{V}$

Here, m is mass and V is volume.
