Answer:
The Ideal gas law
Explanation:
From the given question, we have:
V
where each variable has its usual meaning.
Thus,
V =
where R is the ideal gas constant
cross multiply to have;
PV = nRT
This implies that the volume of the gas is directly proportional to the number of moles of the gas.
Therefore, the law can be used to determine the relationship between the volume and number of moles is the ideal gas law.
