What is the density of a gas if its molar mass is 1.222 g?
At STP 1 mole of a gas occupies 22.4 L So D = m / V = 1.222g / 22.4 L = 0.0546 g/L This is the mathematical answer, but this is impossible. The lightest gas is Hydrogen with a molar mass of 2. No real gas is less than that.
Why is it important to know the mass and volume of gas at STP?
To find it's density
What is the weight of chlorine gas in lbs?
The weight of chlorine gas can vary depending on the volume and temperature. At standard temperature and pressure (STP), the molar mass of chlorine gas (Cl2) is approximately 70.91 grams/mol. To convert this to pounds, you would divide the molar mass by the conversion factor of 453.592 grams per pound. Therefore, the weight of chlorine gas would be approximately 0.156 pounds per mol at STP.
How much does 75.0 L of helium weigh?
The weight of 75.0 L of helium depends on the temperature and pressure at which it is measured. At standard temperature and pressure (STP), which is 0Ā°C and 1 atmosphere, the molar mass of helium is 4.0 grams per mole. Using the ideal gas law, we can calculate the weight by multiplying the molar mass of helium by the number of moles, which is the volume divided by 22.4 L (molar volume at STP). However, if the temperature and pressure are not at STP, additional information is needed to determine the weight.
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 (Nā) is approximately 28.02 grams/mol. To calculate the density (D) of nitrogen gas at STP, you can use the ideal gas law: ļæ½ = Molar mass Molar volume at STP D= Molar volume at STP Molar mass ā ļæ½ = 28.02 ā g/mol 22.4 ā L/mol D= 22.4L/mol 28.02g/mol ā ļæ½ ā 1.25 ā g/L Dā1.25g/L Therefore, the density of nitrogen gas at STP is approximately 1.25 grams per liter.

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 density of a gas if its molar mass is 1.222 g?
At STP 1 mole of a gas occupies 22.4 L So D = m / V = 1.222g / 22.4 L = 0.0546 g/L This is the mathematical answer, but this is impossible. The lightest gas is Hydrogen with a molar mass of 2. No real gas is less than that.

How determine density of gas on hedrogen?
Hydrogen? You need the conditions, pressure and temperature, of the gas. 1 mole of the gas occupies 22.4 liters at STP. The molar mass of hydrogen is 2.0 g/ mole. So the density at STP is 2.0 / 22.4 = 0.0893 g/liter. At any other pressure and temperature you can use the ideal gas law to find the volume of one mole and then find the density.
What are the physical properties of natural gases?
Several properties of methane are:- molar mass: 16,04 g- melting point: -182,5 oC- boiling point: -161,49 oC- density at STP: 0,716 g/L- colorless- odorless
How do you calculate density of chlorine relative to air?
To calculate the density of chlorine relative to air, you would use the formula: Density relative to air = Density of chlorine gas Density of air at the same conditions Density relative to air= Density of air at the same conditions Density of chlorine gas ā The density of a gas can be calculated using the ideal gas law: Density = Molar mass Molar volume Density= Molar volume Molar mass ā Where: Molar mass is the mass of one mole of the substance (in grams per mole). Molar volume is the volume occupied by one mole of the substance at a particular temperature and pressure. For chlorine gas ( ļæ½ ļæ½ 2 Cl 2 ā ), the molar mass is approximately 70.91 ā g/mol 70.91g/mol. The density of air is typically around 1.225 ā kg/m 3 1.225kg/m 3 at standard temperature and pressure (STP), which is defined as 0 , ^\circ \text{C} (273.15 K) and 1 ā atm 1atm pressure. So, to find the density of chlorine gas relative to air, you would substitute the values into the formula: Density relative to air = ( 70.91 ā g/mol ) ( 1.225 ā kg/m 3 ) Ć ( 1 ā mol 1000 ā g ) Density relative to air= (1.225kg/m 3 ) (70.91g/mol) ā Ć( 1000g 1mol ā ) This calculation will give you the density of chlorine gas relative to air under the specified conditions. Keep in mind that the densities and conditions may vary, and you should use the appropriate values for the specific conditions you are considering.
What is the mass of 99.01of NO2 at STP?
If 99,01 is a mass in g this remain unchanged and not dependent from pressure in a closed system.The molar mass nitrogen(II) oxide is 30,01 g.
What is the density of C3H8 at STP?
The molar mass of C3H8 is 44.11g, so 44.11g/22.4L = 1.96g/L I think this is the answer, I'm not sure but I hope this is make you easier :)
