Concept explainers
(a)
Interpretation:
To write an equation that represents the direct proportion, in which D is the proportionality constant.
Concept introduction:
The scope of the measurement depends upon the context and event. Measurement is commonly used as an international system of unit as a comparison framework. Two variables such as mass (m) and volume (V) can be described as directly proportional one on other by the expression m α V. Besides, the term density is given by the mass of the given substance per unit volume. It is denoted by the symbol ‘D’.
(b)
Interpretation:
The density of iron metal is 7.88 g/cm3. The mass of a piece of iron that has a volume of 23.5 cm3 is to be stated.

If you know that each copper atom (radius = 128 pm) has a mass of 1.055 ×10–22 g (you will learn in Chapter 2 how to find the mass of one atom), how manyatoms are there in this cube? What fraction of the cube is filled with atoms? (Orconversely, how much of the lattice is empty space?) Why is there “empty” space in thelattice?(b) Now look at the smallest, repeating unit of the crystal lattice of copper.Knowing that an edge of this cube is 361.47 pm and the density of copper is 8.960g/cm3, calculate the number of copper atoms in this smallest, repeating unitarrow_forward
