It is NO2 I got this question on my castle learning and got it right. Just tryin to help out any other students.
A mole of a gas occupies 22.4 L at STP.
So ... 1.1 g/L x 22.4 L/mole = 24.64 g/mole
The density of ammonia is 0,73 kg/m3 (at 1,013 bar and 15 °C).
At STP, an ideal gas has 22.4 liters per mole. So (2.07 g/L) x (22.4 L/mole) = 46.368 g/mole
Oxygen Gas (O2)
flourine
Density of CO2 at STP = 44.01 g/mol divided by the 22.4 liters. 1.96 grams/Liter
We know that one mole of any gas at STP occupies 22.4 liters of volume. We also know that one mole of carbon dioxide is 44.01 grams of CO2. If there are 44.01 grams of this gas in 22.4 liters at STP, then there will be about 0.98 grams of CO2 in half a liter (500 ml) of the gas at STP.
Argon has a density of 1.78 g/L at STP. One gallon =3.785 liters. So 1.78 g * 3.785 = 6.74 grams per gallon.
Fluorine is a gas at STP. The density is (38 g / 22.4 L) x (1 pound / 454 g) = 0.00374 pounds / Liter
At STP, water is a liquid with a density of 1000.000 grams per liter. The gram molecular mass of water is 18.01528. Therefore, the number of moles of water in one liter is 1000.000/18.01528 or 55.5084 moles. The number of molecules in one liter is therefore 55.5084 X 6.022 X 1023 or about 3.34272 X 1025, and the volume of one molecule is therefore 1 [exact]/3.34272 X 1025 or 2.99158 X 10-24 liter.
Density of CO2 at STP = 44.01 g/mol divided by the 22.4 liters. 1.96 grams/Liter
1.783 grams/liter x 22.4 liters/mole = 40 grams/mole = Argon

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.

Fluorine is a gas at STP. The density is (38 g / 22.4 L) x (1 pound / 454 g) = 0.00374 pounds / Liter
The estimated value of the density of francium at STP is 1,87 g/cm3.
