The solubility of nitrogen gas "N2" in water at 20oC and 520 mmHg is 5.0×10-4 mol/L. The Henry's law constant (in mol/L.atm) at 20oC for the solubility of nitrogen gas in water is: A) 7.3×10-4 B) 7.1×10-4 C) 6.9×10-4 D) 6.7×10-4 Show steps please.
At 340 K, Kp = 69 for the reaction H2(g) + I2(g) ->2HI(g). 50.0 g of HI is injected into an evacuated 5.00-L rigid cylinder at 340 K. What is the total pressure inside the cylinder when the system comes to equilibrium?
An ideal gas is in a cylinder with a volume of 250.0 mL at a temperature of 25 ºC and a pressure of 700 torr. The gas is expanded to a volume of 1.0 L and the temperature increased to 500 ºC.
