What is the volume occupied by a mole of an ideal gas,if the pressure is 626 mmHg and the temperature is 25.0°C?

Question

Quizplus · Accepted Answer

The volume occupied by a mole of an ideal gas can be calculated using the ideal gas law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin. Given that the pressure is 626 mmHg (which is equivalent to 626/760 atm, since 1 atm = 760 mmHg), the temperature is 25.0°C (which is equivalent to 298.15 K, since you must add 273.15 to convert from Celsius to Kelvin), and n = 1 mole, we can solve for V. Using R = 0.0821 L·atm/(mol·K), the calculation yields a volume close to 29.7 L, making choice A correct.
