To solve this problem, we can use the combined gas law, which relates the pressure, volume, and temperature of a gas. The combined gas law is given by: where:- and are the initial and final pressures,- and are the initial and final volumes,- and are the initial and final temperatures in Kelvin.First, we need to convert the temperatures from Celsius to Kelvin: Next, we plug in the known values into the combined gas law equation: We need to find . Rearrange the combined gas law to solve for : Substitute the values into the equation: Calculate the result: Considering significant figures, the initial volume (1200 L) has 2 significant figures, so the final answer should also be reported with 2 significant figures: Therefore, the correct answer is:
