The vapor pressure of liquid octane, C8H18, is 40.0 mm Hg at 318 K. A sample of C8H18 is placed in a closed, evacuated container of constant volume at a temperature of 446 K. It is found that all of the C8H18 is in the vapor phase and that the pressure is 60.0 mm Hg. If the temperature in the container is reduced to 318 K, which of the following statements are correct? Choose all that apply. The pressure in...

10 mol NH3(g) was placed in a previously evacuated 20-L container. After a sudden temperature rise to 961.4K, 80% of ammonia dissociated into hydrogen and nitrogen according to the reaction: 2/3 NH3(g) ------> 1/3 N2(g) + H2(g) What is the total pressure of the mixture, if all gasses are ideal? (correct sig-figs)

A container with volume 1.78 L is initially evacuated. Then it is filled with 0.246 g of N2. Assume that the pressure of the gas is low enough for the gas to obey the ideal-gas law to a high degree of accuracy. Part AIf the root-mean-square speed of the gas molecules is 192 m/s, what is the pressure of the gas?
A container holding 10.0 kg of water is placed in a closed space station containing an air volume of 2500 m3 of completely dry air. Eventually the water either all evaporates or comes into vapor pressure equilibrium with the air which is kept at a steady 22.0°C. What is the final humidity?
