If 11.7 g of NH3 is isolated in a flask at a pressure of 1.75 bar, what will the density of the gas be at a temperature of 25C?
given
pressure (P) = 1.5 bar = 1.48 atm
molar mass of NH3(M) = 17 g/mole
T = 25 + 273 = 298 K
density (d) = ?
we know
density (d) = PM / RT = (1.48 * 17) / (0.0821 * 298) =1.03 g/lit

Ammonia, NH3(g)NH3(g), at a pressure of 1.13 bar, is placed in a container at a certain temperature. When equilibrium is established at that temperature, the pressure of H2(g)H2(g) is 0.620 bar. Part A Determine the value of KPKP for the decomposition of NH3NH3 at that temperature: 2NH3(g)⇌3H2(g)+N2(g)2NH3(g)⇌3H2(g)+N2(g) Express your answer in squared bars to three significant figures. Please show steps and the final units in bar^2

A 1.75 g sample of an unknown gas at 33 ∘C and 1.05 atm is stored in a 1.15 L flask. What is the density of the gas? What is the molar mass of the gas?
8. A experiment is performed on an isolated gas. During the experiment, the gas pressure of an isolated gas in a constant volume flask (V=0.500L) was measured using a gas pressure sensor as the temperature of the gas was varied. The pressure vs volume for the graph for the experiment is shown below, as well as the corresponding curve fit generated. NOTE: The gas temperature inside the syringe was a constant 22.5°C during this experiment. i. Express value of the...
