The answer is (e) all of the samples have same volumes at STP.
What is STP?
At standard temperature and pressure (STP), all gases have the same volume, regardless of their mass or chemical composition. STP is defined as a temperature of 273 K (0°C) and a pressure of 1 atm.
At STP, all gases have a density of approximately 1.225 kg/m3, and the volume of a gas is directly proportional to its number of moles. Therefore, any sample of a gas at STP will have the same volume as any other sample of the same number of moles.
To determine the number of moles in a sample of a gas, you can use the ideal gas law, which states that the volume of a gas is directly proportional to the number of moles of the gas and inversely proportional to the pressure and temperature:
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 ideal gas constant, and T is the temperature of the gas.
If you know the mass and molecular weight of the gas, you can also use the following equation to calculate the number of moles:
n = (m) / (MW)
where m is the mass of the gas, and MW is the molecular weight of the gas.
Therefore, to determine which of the given samples would have the greatest volume at STP, you would need to calculate the number of moles in each sample and compare them. All of the samples would have the same volume if they had the same number of moles.
Hence, all of the samples have the same volume at STP.
