A. 2 moles of gas
B. 1 mole of gas
C. 5 moles of gas
D. 3moles of gas
¨ Effective volume is usually taken for 1 mole of gas. The effective volume of a gas is the volume it occupies under specific conditions of temperature and pressure, which are typically standard temperature and pressure (STP). STP is defined as a temperature of 0°C (273.15 K) and a pressure of 1 atmosphere (atm). The effective volume of 1 mole of gas at STP is 22.4 liters (L), also known as the molar volume of a gas. This value is obtained from the ideal gas law, 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.
