Question

The experiment is about testing the ideal gas law (magnesium ribbon experiment)

Which of the following deviations from the experiment would most considerably cause an
increase in the final calculated %yield of the Mg(s)?
Placing 13.0 mL instead of 10.0 mL of 6.0 M HCl into the eudiometer.
Immediately reading the volume of gas right after the reaction ceased.
Not adding enough water to fill the eudiometer to the brim, leaving a headspace after
inverting the eudiometer.
Consciously inserting 15.0 mg of folded Mg ribbon instead of the prescribed 20 to 30
mg into the eudiometer.
