• ### which of the following gases has a density of 2.104 g L 1

Apr 16, 2011 · 133 kPa * 1 L = n * 8.3145 * 303 K. n= no. of mol = 0.053 mols. mol =mass /molar mass. molar mass = mass /mols = 2.104 /0.053 = 39.698 gm/mol. so from the periodic table we will know that the gas is Ar which has a molar mass of 39.7gm/mol.

• ### Which gas is most dense at 1.00 atm and 298 K? Yahoo

Oct 25, 2009 · Answers. The answer is choice D, so thats the only one im working out. MM = 80.0 P = 1.00 atm R = .08206 T = 298 K Now plug the numbers in the formula(80.0) (1) / (.08206) (298) d = 3.2 g The rest of the choices have a density below 3.2, so SO3 is your answer.

• ### What Is the Density of Air at STP? ThoughtCo

The ISA or International Standard Atmosphere states the density of air is 1.225 kg/m3 at sea level and 15 degrees C. The IUPAC uses an air density of 1.2754 kg/m3 at 0 degrees C and 100 kPa for dry air. Density is affected not only by temperature and pressure but also by the amount of water vapor in the air.
