Chapter 9, Problem 9.63QP

Interpretation Introduction

Interpretation:

The required mass of ${\text{CaI}}_{\text{2}}$ to prepare a $\text{5}{\text{.00×10}}^{\text{2}}\text{mL}$ $\text{2}\text{.80 M}$ ${\text{CaI}}_{\text{2}}$ solution has to be determined.

Concept introduction:

Mole

The mole of the solute is calculated by multiplication of concentration of solution and volume of the solution and it is,

$\text{Mole}\text{=}\text{Concentration}\text{(M)×}\text{volume}\text{(L)}$

The mass of compound is given by the multiplication of mole of the compound and molar mass of the compound in gram.

$\text{Mass}\text{=}\text{Mole×}\text{Molar}\text{mass}$
