How to Calculate Pressure Inside a Container Holding Argon Gas

What is the pressure inside a 35.5 L container holding 101.5 kg of argon gas at 23.0 °C?

Which of the following is the correct pressure inside the container?

A. 1761.44 kPa

B. 1706.28 atm

Answer:

The pressure inside the container is 1761.44 kPa.

To calculate the pressure inside a 35.5 L container holding 101.5 kg of argon gas at 23.0 °C, we can use the ideal gas law equation, PV = nRT. First, convert the mass of argon gas to moles by dividing the mass by the molar mass of argon (39.95 g/mol). Next, convert the temperature from Celsius to Kelvin by adding 273.15.

Now, plug the values into the ideal gas law equation and solve for pressure. The pressure inside the container is 1761.44 kPa.
