To find it's density
The volume of 10.9 mol of helium at STP is 50 litres.
To find the volume of 76g of F2 at STP, we first need to determine the number of moles of F2 using the molar mass. The molar mass of F2 is 38 g/mol. 76g / 38 g/mol = 2 moles of F2. At STP, 1 mole of any gas occupies 22.4 L. Therefore, 2 moles of F2 would occupy 44.8 L at STP.
The molar mass of water (H2O) is approximately 18.015 grams per mole. The volume of one mole of water at standard temperature and pressure (STP) is about 18.0 milliliters.
The molar volume of a gas at STP (standard temperature and pressure) is 22.4 L/mol. To calculate the molar mass of the gas, you can use the formula: Molar mass = (mass of gas / volume of gas) x molar volume at STP. In this case, with a mass of 60g and a volume of 5.6 dm3, the molar mass would be 60g/5.6dm3 x 22.4L/mol = 240 g/mol. Vapour density is calculated as 2 x molar mass, so in this case the vapour density would be 480 g/mol.
To find the mass of nitrogen gas, you need to know the density of nitrogen gas at the given conditions (typically at STP - standard temperature and pressure). The density of nitrogen at STP is about 1.25 g/L. You can use this value to calculate the mass by multiplying the density by the volume given in milliliters.
Gas
The mass of 43,7 L of helium at STP is 7.8 g.
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.

To find the volume of 76g of F2 at STP, we first need to determine the number of moles of F2 using the molar mass. The molar mass of F2 is 38 g/mol. 76g / 38 g/mol = 2 moles of F2. At STP, 1 mole of any gas occupies 22.4 L. Therefore, 2 moles of F2 would occupy 44.8 L at STP.
The molar volume of a gas at STP is 22.4 liters/mol. The molar mass of hydrogen bromide is 80.9 g/mol. Therefore, the density of hydrogen bromide at STP is 80.9 g/mol / 22.4 L/mol = 3.61 g/L.
At STP conditions (standard temperature and pressure), the volume occupied by 1 mole of ideal gas is 22.4 liters. Since the molar mass of SO2 is approximately 64 g/mol, 11 g of SO2 is about 0.172 moles. Therefore, the volume of 11 g of SO2 at STP would be approximately 3.85 liters.
At standard temperature and pressure (STP), the gas that occupies the highest volume is hydrogen.
The molar mass of water (H2O) is approximately 18.015 grams per mole. The volume of one mole of water at standard temperature and pressure (STP) is about 18.0 milliliters.
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.
The molar volume of a gas at STP (standard temperature and pressure) is 22.4 L/mol. To calculate the molar mass of the gas, you can use the formula: Molar mass = (mass of gas / volume of gas) x molar volume at STP. In this case, with a mass of 60g and a volume of 5.6 dm3, the molar mass would be 60g/5.6dm3 x 22.4L/mol = 240 g/mol. Vapour density is calculated as 2 x molar mass, so in this case the vapour density would be 480 g/mol.
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.
