Chapter 4, Problem 4.63QE

(a)

Interpretation Introduction

Interpretation:

The number of moles of solute in $\text{34 mL of a 0}{\text{.11 M K}}_{\text{2}}{\text{SO}}_{\text{4}}$ solution has to be calculated.

Concept introduction:

Molarity: Dividing moles of solute by the volume of solution in Liter.

  $\text{Molarity}\text{=}\frac{\text{Moles}\text{of}\text{solute}}{\text{Volume of solution in L}}$

(b)

Interpretation Introduction

Interpretation:

The number of moles of solute in $\text{10 mL of an 8}\text{.3 M}\text{NaCl}$ solution has to be calculated.

Concept introduction:

Molarity: Dividing moles of solute by the volume of solution in Liter.

  $\text{Molarity}\text{=}\frac{\text{Moles}\text{of}\text{solute}}{\text{Volume of solution in L}}$
