Answer:
3. Moles.
Explanation:
Let's see an example of the gas law formula:
[tex]PV=nRT;\text{ \lparen ideal gas law\rparen.}[/tex]P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is the temperature on Kelvin scale.
The quantity of a gas that can be measured in this calculation would be the number of moles (n). This amount can come from a given mass with its molar mass to obtain moles.
The answer would be 3. Moles.
