so we just finished the epxeritment on Tuesday and im working on trying to do the calculations but my lab professor told us that when we we record the time on our phones we should make sure to do it in laps so this is an example of what i got for my 1st for the experiment for the lap time. 1st trial: 2ml O2 produced= 1:47.10 ; 4ml O2 produced= 1:44.00; 6 ml O2 produced; 1:30.76.
Theres more but my question is that how do you convert these lap times into seconds? I tried to do it and asked my lab partner what he got but he got something way different for 2ml O2 produced in seconds which was 107.10 seconds. I didnt get the same answer and Im not sure if i had to use a certain rate of reaction formula to get the same answer as him. Im just really trying to understand this my lab professor didn't fully explain it:(

How "way different"? 1 min 47.1 sec = 107.1 sec.

Every minute is 60 seconds. So 1 min 47.10 seconds = 60 + 47.10 = 107.10 seconds.
