Question

An old 0.500 L lecture bottle of argon was found in a lab and needed for a reaction. A pressure regulator indicated a pressure of 46.5 psi, and the lab was at room temperature (25°C). What mass of gaseous argon was left in the lecture bottle? a) Not enough information is provided to calculate the mass of argon. b) The mass of gaseous argon can be determined using the ideal gas law. c) The pressure and temperature are not relevant to calculate the mass of argon. d) The mass of gaseous argon is constant, regardless of pressure and temperature.

Answer 1

To calculate the mass of gaseous argon left in the lecture bottle, we need to use the ideal gas law. However, we do not have enough information to calculate the mass. (Option a)

Step-by-step explanation:

To calculate the mass of gaseous argon left in the lecture bottle, we need to use the ideal gas law. The ideal gas law equation is 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.

We are given the volume (0.500 L) and pressure (46.5 psi) of the argon in the lecture bottle. However, since we are not given the number of moles or the gas constant, we do not have enough information to calculate the mass of gaseous argon.

Therefore, the correct answer is a) Not enough information is provided to calculate the mass of argon.
