(PavelTa = P2 V₂ / Te). Divide volume found at STP by the number of moles to get the expermentally determined molar udume at STP * The accepted value of the molar volume of a agas at STP is 22.4L. Find your percent error. 4 Error = x 100 Theoretical Value - Actual / known / True Value
you will reac magnesium with an excess of hydrochloric acid to produce the substances shown: Mg(s) + HCl(aq) MgCl2(aq) + H2(g) You will make an experimental determination of the number of moles of hydroge and volume occupied by these molecules. The combined gas law will be used to correct this volume of hydrogen since it laboratory conditions instead of STP. Your corrected volume and your calcula hydrogen will be used to calculate the molar volume of the hydrogen gas. Since the hydrogen gas is collected by downward displacement of water. Com the experiment the gas in the tube will really be a mixture of hydrogen gas a then subtract the water vapor pressure from the atmospheric pressure. Wat from a table since it depends only on the temperature of the water. Pwater P2 (for calculation) Patm (table) Tem carl Dressure
