Chapter 16, Problem 121AE

Interpretation Introduction

Interpretation: The formula of the compound and the relative numbers of the ${\text{Ti}}^{2+}$ and ${\text{Ti}}^{3+}$ ions needs to be determined.

Concept Introduction: From the mass and molar mass, number of moles can be calculated as follows:

  $n=\frac{m}{M}$

Here, m is mass and M is molar mass.

Also, the mass percentage can be related to mass of atom say A and compound as follows:

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