Chapter 12, Problem 12.148P

Interpretation Introduction

Interpretation:

The volume of gaseous ${\text{H}}_{\text{2}}$ (at STP) that can be packed into the spaces of $1{\text{ dm}}^3$ of palladium metal is to be calculated.

Concept introduction:

Crystal structure or lattice is the three-dimensional representation of atoms and molecules arranged in a particular manner. The unit cell is the smallest part of the lattice that is repeated in all directions to yield the crystal lattice. There are 3 types of cubic unit cells as follows:

1. The simple cubic unit cell

2. Body-centered unit cell

3. Face-centered unit cell

The formula to calculate the mass of a compound is as follows:

$\text{Mass of compound}=\left(\text{volume of compound}\right)\left(\text{density of compound}\right)$
