Chapter 3, Problem 3.24QP

(a)

Interpretation Introduction

Interpretation: The moles of uranium in $1.0\text{mol}$ of the given compounds are to be calculated.

Concept introduction: A mole of a substance is the quantity of a substance which contains the same number of particles as the number of carbon atoms in exactly 12 grams for the carbon-12 isotopes. A mole of particles contains Avogadro’s number $\left(6.022\times {10}^{23}\right)$ of particles.

To determine: The moles of uranium in one mol of carnotite $\left({\text{K}}_{\text{2}}{\left({\text{UO}}_{\text{2}}\right)}_{\text{2}}{\left({\text{VO}}_{\text{4}}\right)}_{\text{2}}\right)$.

(b)

Interpretation Introduction

To determine: The moles of uranium in one mol of uranophone $\left({\text{CaU}}_{\text{2}}{\text{Si}}_{\text{2}}{\text{O}}_{\text{11}}\right)$.

(c)

Interpretation Introduction

To determine: The moles of uranium in one mol of Autunite $\left(\text{Ca}{\left({\text{UO}}_{\text{2}}\right)}_{\text{2}}{\left({\text{PO}}_{\text{4}}\right)}_{\text{2}}\right)$.
