Chapter 6, Problem 6.47AP

Interpretation Introduction

Interpretation:

The amount of moles ${\text{CO}}_{\text{2}}$ should be determined from the air by 1.0 Kg of $\text{NaOH}$& calcium hydroxide $\text{Ca}{\left(\text{OH}\right)}_{\text{2}}$.

Concept Introduction:

The Mole and Avogadro’s number

•For convenience in considering reactions and calculating quantities, chemists think in terms of moles of substances.

•A mole is a quantity of particles defined as Avogadro’s number of particles or formula units of elements or compounds.

•The molecular or formula weight of a compound is the sum of the mass of all atoms in the formula.

•A mole also happens to be 22.4 L of an ideal gas under standard conditions, so 22.4 L of ideal gas represent one gram formula weight of the compound.
