To calculate the universal gas constant from the ideal gas law, you would need the temperature of the gas. The ideal gas law is represented as PV = nRT, where: - P is the pressure of the gas, - V is the volume of the gas, - n is the number of moles of the gas, - R is the universal gas constant, and - T is the temperature of the gas in Kelvin. Knowing the pressure, volume, and number of moles allows you to set up the ideal gas law equation, but to find the value of the universal gas constant (R), you need to have the temperature of the gas in Kelvin. This is because the units of the gas constant R are dependent on the units used for pressure, volume, and temperature in the ideal gas law equation. Therefore, to determine the universal gas constant from the ideal gas law, you must have the temperature of the gas in Kelvin as one of the required pieces of information.
