Question

The expression below was formed by combining different gas laws. V is proportional to StartFraction n T over P EndFraction. Which law was used to determine the relationship between the volume and the number of moles in this equation?

Answer 1

Answer:

The Ideal gas law

Explanation:

From the given question, we have:

V $\alpha$ $\frac{nT}{P}$

where each variable has its usual meaning.

Thus,

V = $\frac{nRT}{P}$

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.
