Answer:
Wave frequency can be measured by counting the number of crests (high points) of waves that pass the fixed point in 1 second or some other time period. The higher the number is, the greater the frequency of the waves. ... For example, it is the distance between two adjacent crests in the transverse waves in the diagram.
Explanation:
First, we calculate for the total volume of aluminum. The
volume of a cube is:
V = s * s * s = s^3
V = (2.70 cm)^3
V = 19.683 cm^3
Assuming atmospheric temperature, the density of aluminum is
about 2.70 g / cm^3. Therefore the equivalent mass of aluminum is:
m = 19.683 cm^3 * 2.70 g / cm^3
m = 53.1441 g
The molar mass of aluminum is 27 g / mol. Therefore the
number of moles is:
n = 53.1441 g / (27 g / mol)
n = 1.9683 mol
Given the number of moles, we can calculate for the number of
atoms using Avogadro’s number.
atoms = 1.9683 mol * (6.022 * 10^23 atoms / mol)
<span>atoms = 11.85 * 10^23 atoms (ANSWER)</span>
