Document Summary

Exert a force when it collides with a surface or other gaseous particles. R is the gas constant and is the same for all gases. Used to define a volume of an ideal gas. Stp= standard temperature and pressure (not provided on the exam) Volume of 1mol of gas at stp. Volume of a gas at stp is called the molar volume. Notes: only need to know the temperature, molecular mass, moles and pressure to find (volume is unnecessary) Few gases are pure, most are mixture so the mixture can be thought of as one gas. Using percent by volumes of the gases in the mixture, one can find the partial. Dalton"s law pressures of the components in the mixture. The ratio of partial pressure a single gas contributes and total pressure is. The partial pressure of a component of the gas is its mole fraction multiplied by the total pressure.
