<u>Answer:</u> The number of gold atoms per cubic centimeters in the given alloy is
<u>Explanation:</u>
To calculate the number of gold atoms per cubic centimeters for te given silver-gold alloy, we use the equation:
where,
= number of gold atoms per cubic centimeters
= Avogadro's number =
= Mass percent of gold in the alloy = 42 %
= Density of pure gold =
= Density of pure silver =
= molar mass of gold = 196.97 g/mol
Putting values in above equation, we get:
Hence, the number of gold atoms per cubic centimeters in the given alloy is

Dimensional analysis can only be used for time, distance, mass, speed, volume, and chemical quantities: False.
<h3>What is
dimensional analysis?</h3>
A dimensional analysis can be defined as an analysis of the relationships that exist between different physical quantities by identifying their fundamental (base) quantities, especially for the purpose of inferences.
Dimensional analysis is also referred to as unit-factor method or factor-label method and it is typically used to convert a different type of unit to another.
Generally, dimensional analysis can only be used for the following physical quantities:
In conclusion, a dimensional analysis cannot be used for chemical quantities such as a mole i.e it has no dimensional formula.
