the total volume of the gas bags of the german dirigible hindenberg, was 2.0 * 10^5m^3. how many grams of H2 would be required to fill them at 20 celcius and 1.00 atm pressure? hint convert m^3>cm^3>mL>L.
Determination of the partial pressures of the gases - Find the partial pressure of each of these gases in the final product mixture.
In a gas mixture the partial pressures are nitrogen 425 torr, oxigen 115 torr, and hellium 225 torr. What is the total pressure (atm) exerted by the gas mixture?
A quantity of gas under a pressure of 1.78 atm has a volume of 550 cm square. the pressure is increased 2.50atm while the pressure remains constant what is the new volume.
