Document Summary

Avogadro"s law states that one mole of any ideal gas always occupies the same volume at a given temperature and pressure, regardless of the gas in question. Equal volumes of different gases at the same temperature and pressure contain the same number of moles. Molar volume of an ideal gas under standard conditions is 22. 4l. Standard temperature and pressure (stp) is: 0 c (273. 15k), 1 atm (101. 33kpa) Density is the mass occupied per unit volume. Substitute mass formula into density formula, the rearrange for volume and substitute it into the ideal gas law. Each of the constituents in a gas mixture is said to exhibit a partial pressure that contributes to the total pressure. Dalton"s law of partial pressure: the total pressure exerted by a mixture of gases is the sum of all the partial pressures of these gases. Mole fraction ni = mol of an individual constituent in a gas nt = moles of the mixture in total.
