53.5 g of an ideal gas of molecular weight = 10.5 g/mol is confined at a pressure of 50 kPa. The density of the gas is 0.164 g/L. Compute the temperature of the gas in degrees Celsius.
What is the pressure (in millimeters of mercury) inside a container of a gas connected to an open-end manometer filled with decane (density = 0.7300 g/cm3) when the level in the arm connected to the container is 765.3 mm in height higher than the ..
The valve between the 2.00L bulb, in which the gas pressure is 1.00 atm, and the 3.00L bulb, in which the gas pressure is 1.50 atm, is opened. What is the final pressure in the two bulbs, the temperature remaining constant
