If a student loses magnesium oxide ash during the heating process, what effect will that have on the calculated ratio of magnesium to oxygen?

Expert Solution

Answer: If there is loss in magnisium oxide ash during heating process there must be decrease in the ratio of magnesium to oxygen.

The ratio of Magnesium to oxide when no loss if there is should be close to 1:1.

Viz. mass of Magnisium= 2.39g

mass of Magnisium oxide= 3.78g

mass of oxygen= 1.39g

Number of moles of Magnisium= 2.39/24= 0.0995

Number of moles of oxygen= 1.39/16= 0.0868

According to this calculation, this gives Approximately 1:1 ratio of Mg: O.

While in case of loss of magnisium oxide ash during heating causes change in the moles ratio of Mg to O and results in the decrease of ratio due to loss in ash.

If sample was lost during the heating process, would the mass of water lost be too high or too low? Would this experimental error result in a value of n that is too large or too small? If some water remained at the end of the heating process, would the calculated mass of water lost be too high or too low? Would this experimental error result in a value of n that is too large or too small?
