What is the mass of 39.6 dm3 of argon gas collected at STP?
The molar volume of any ideal gas at standard temperature and pressure (STP) is 22.4 L/mol. Converting 39.6 dm3 to liters gives 39.6 L. To find the mass of argon gas, we calculate the number of moles using the ideal gas equation (PV = nRT) and then multiply by the molar mass of argon.
What is the mass of 1 liter of chlorine(g) at STP?
At standard temperature and pressure (STP), 1 mole of an ideal gas occupies 22.4 liters. The molar mass of chlorine (Cl₂) is approximately 70.9 g/mol. Therefore, 1 liter of chlorine gas at STP would have a mass of about 3.18 grams, calculated as (70.9 g/mol) / (22.4 L/mol).
How much 1 mol of O2 gas?
One mole of O₂ gas occupies approximately 22.4 liters at standard temperature and pressure (STP), which is 0 degrees Celsius and 1 atmosphere of pressure. The molar mass of O₂ is about 32 grams, meaning that 1 mole of O₂ weighs 32 grams. Thus, under STP conditions, 1 mole of O₂ gas will have both a specific volume and mass.
What is the density at STP of hydrogen sulfide gas (H2S)in grams per liter?
The density of hydrogen sulfide gas (H2S) at standard temperature and pressure (STP) is approximately 1.363 grams per liter. This value can be derived from the molar mass of H2S, which is about 34.08 g/mol, and the fact that one mole of gas occupies 22.4 liters at STP. Thus, the density is calculated as the molar mass divided by the molar volume.
What is the density at STP of (H2S) in grams per liter?
At standard temperature and pressure (STP), the density of hydrogen sulfide (H₂S) is approximately 1.363 grams per liter. This value can be calculated using the molar mass of H₂S, which is about 34.08 g/mol, and the ideal gas law, considering that one mole of gas occupies 22.414 liters at STP. Therefore, the density is derived by dividing the molar mass by the volume at STP.
What is the mass of 43.7 L of helium at STP?
The mass of 43,7 L of helium at STP is 7.8 g.
Why is nitrogen gas at STP less dense than Xe gas at STP?
Nitrogen gas at STP is less dense than xenon gas at STP because nitrogen has a lower atomic mass and thus lighter molecules, leading to lower density. Additionally, xenon is a noble gas with a higher atomic mass and larger atomic radius, contributing to its higher density.
What is the mass of ethane gas inside a 5.00 L vessel at STP?
The molar volume of a gas at STP (Standard Temperature and Pressure) is 22.4 L. Ethane gas has a molar mass of 30.07 g/mol. Therefore, the mass of ethane gas in a 5.00 L vessel at STP can be calculated as (5.00 L / 22.4 L) * 30.07 g/mol.
In what phase would a substance with a volume of 25.00mL and a mass of 78.05g be at STP?

What is the mass of 39.6 dm3 of argon gas collected at STP?
The molar volume of any ideal gas at standard temperature and pressure (STP) is 22.4 L/mol. Converting 39.6 dm3 to liters gives 39.6 L. To find the mass of argon gas, we calculate the number of moles using the ideal gas equation (PV = nRT) and then multiply by the molar mass of argon.
The molar mass of a gas at STP is the density of that gas?
Density is mass per volume. Density of gas is mostly the same in mol/volume. The molecular mass play large role in the different of density. Weak intermolecular force and interaction among different species of gases may give extra additional to the different in density of mix gas but at very small fraction.
What is the volume at STP of a 49.6 gram sample of acetylene gas?
To find the volume of the acetylene gas at STP, we can use the ideal gas law equation: PV = nRT. First, we must convert the given mass of acetylene gas to moles using its molar mass. Then, knowing STP conditions (standard temperature = 273 K and standard pressure = 1 atm), we can calculate the volume.
Calculate the density of nitrogen gas, in grams per liter, at STP?
At Standard Temperature and Pressure (STP), which is defined as 0 degrees Celsius (273.15 Kelvin) and 1 atmosphere pressure, the molar volume of an ideal gas is approximately 22.4 liters/mol. The molar mass of nitrogen gas (N₂) is approximately 28.02 grams/mol. To calculate the density (D) of nitrogen gas at STP, you can use the ideal gas law: � = Molar mass Molar volume at STP D= Molar volume at STP Molar mass � = 28.02 g/mol 22.4 L/mol D= 22.4L/mol 28.02g/mol � ≈ 1.25 g/L D≈1.25g/L Therefore, the density of nitrogen gas at STP is approximately 1.25 grams per liter.
A 22.0 gram sample of an unknown gas occupies 11.2 liters at STP What is the identity of the gas?
Based on the ideal gas law, we can calculate the molar mass of the gas to determine its identity. Using the formula PV = nRT and knowing that at STP, the pressure is 1 atm and the temperature is 273 K, we can find the number of moles of gas. Then, dividing the mass of the gas by the number of moles will give us the molar mass, allowing us to identify the gas.
Is argon a solid at STP?
Argon is a gas at STP. It becomes a liquid below -186oC and solid below -190oC at StP
What does avogadros law say about a gas at STP?
1 mole of gas at STP occupies 22.4 liters.
What is the density at STP of (H2S) in grams per liter?
At standard temperature and pressure (STP), the density of hydrogen sulfide (H₂S) is approximately 1.363 grams per liter. This value can be calculated using the molar mass of H₂S, which is about 34.08 g/mol, and the ideal gas law, considering that one mole of gas occupies 22.414 liters at STP. Therefore, the density is derived by dividing the molar mass by the volume at STP.
