Final answer:
To calculate the change in volume of a gas, use the ideal gas law equation: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin. In this case, since the pressure is constant, the change in volume can be found by subtracting the initial volume from the final volume.
Step-by-step explanation:
To calculate the change in volume of a gas, you need to use the ideal gas law equation, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.
In the given question, the pressure is constant and the volume increases from 9.00 L to 15.00 L. To find the change in volume, subtract the initial volume from the final volume: 15.00 L - 9.00 L = 6.00 L.
Therefore, the change in volume of the gas is 6.00 L.
