Calculate the true molar volume of an ideal gas at standard temperature and pressure. Use the ideal gas law for calculations. Express the final result as the in L per 1 mole of gas.
a student collectedhydrogen gas in a buret by displacing water at 26.0c. the buretcould not be submerged deep enough in
Butane is used as the fuel in pocket cigarette lighters. It is a liquid when stored under pressure in the lighter, but vaporises when the valve is opened. Combustion of butane is represented by the equation:
A quantity of N2 occupies a volume of 1.5L at 300K and 1.2atm. The gas expands to a volume of 3.1L as the result of a change in both temperature and pressure.
