  1. Experiment - The Empirical Formula of Magnesium Oxide

    To reach molar ratios, the number of moles of magnesium and oxygen were reached and simplified into the lowest whole number ratios. The empirical formula of magnesium oxide was then decided. During data processing, the percentage uncertainties associated with masses were found so that the percentage uncertainties of the number of moles were concluded.

    For example, the uncertainty of constant of Pressure and Volume, it had 8% of uncertainties so the biggest constancy was 1200 (highest constancy was 46,900 �3750 - the lowest constancy was 45,700 �3660)

  1. IB Chemistry - Charles' Law Lab Report

    According to the theory, at 82?, the height (volume) must be the greatest but in the experiment, the height showed the lowest scale. Moreover, it does not show a graphically straight line which means there was something wrong with the temperature.

  2. Determining the empirical formula of magnesium oxide lab

    in trial two, human error does not play a huge role in this lab, because all measurements were taken with a digital instrument. Therefore the errors in this lab are mainly systematic, but could also be due to an incomplete reaction occurring due to impartial combustion.

  1. Finding the empirical formula of magnesium oxide

    Record the mass of crucible and lid once it has cooled. Do not handle it with your hands. 4. A magnesium ribbon which was weighted 0.3g using electronic balance was cleansed thoroughly with sandpaper to remove any oxide coating. The ribbon was fitted into the bottom of the crucible.

  2. Chemistry Investigation to find the Empirical Formula of Magnesium Oxide

    with oxygen was used to calculate the empirical formulae and to obtain the uncertainties. The tables are arranged in a chronological order of the process of data. With the process of data will produce the empirical formulae which will be used to compare with a theoretical value.
