Experiment 1: Measuring the Rate of Photosynthesis For the first experiment, what was the change in volume from 00:00:00 to 00:00:30? Calculate the change in volume by subtracting the later gas volume from the earlier gas volume. Record your result for a later question. Note: depending on when you started the timer there is a range of possible volumes. Pick the answer that is closest to yours.

Simone Waters · Answer 1

To answer this problem, we would to look at the table of results. Suppose that we have the following result:

Rate of Photosynthesis Results:

Time Volume in Gas Syringe (mL)

00:00:00 0.6

00:00:30 4.8

00:01:00 9.4

00:01:30 13.8

00:02:00 18.2

So we simply have to subtract the volume at 00:00:30 with the volume at 00:00:0o, so that

change in volume = 4.8 - 0.6

change in volume = 4.2 mL
