Final answer:
To find the volume of Xe gas, we can use the ideal gas law equation PV = nRT. First, convert the given pressure to atm. Next, calculate the number of moles using the formula n = m / M. Finally, substitute the values into the ideal gas law equation to find the volume.
Step-by-step explanation:
The given question asks for the volume of Xe gas when 2.72 grams of Xe gas are collected at 723 mm Hg and 20°C. To solve this, we can use the ideal gas law equation, PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
First, we need to convert the given pressure from mm Hg to atm by dividing it by 760 mm Hg. Now we have the pressure in atm and can rearrange the ideal gas law equation to solve for volume: V = nRT / P. Next, we need to determine the number of moles of Xe gas.
To do this, we can use the formula n = m / M, where n is the number of moles, m is the mass, and M is the molar mass of the substance. The molar mass of Xe is 131.29 g/mol. Plug in the values and calculate the number of moles. Finally, substitute the values into the rearranged ideal gas law equation to find the volume of the Xe gas.
