Three students are asked to discuss the percent errors obtained
from this lab and explain what would account for the discrepancies
seen, if any. Select the student that employs correct scientific
reasoning
• Student 1: A source of error could occur if the valve did not fully seal and allowed
gas to escape, this would lower the measured pressure and therefore lower the
molar volume calculated.
Student 2: A source of error could come from adding too much water in the room
temperature water bath causing more hydrogen to be formed and falsely
increasing the molar volume.
Student 3: A source of error that causes the molar volume to be wrong is if the
magnesium was the limiting reactant and therefore not enough hydrogen gas
would be produced.

The goal of this experiment was to answer the question "what is the effect of a gas' temperature on its volume? " you formulated the hypothesis below. hypothesis: if a fixed amount of gas is heated, then the volume will increase because the heat will cause the molecules of gas to move faster and further apart. to test this hypothesis, you changed the of the gas between 0 and 100°c (273 and 373 k) and calculated the resulting of the gas.
