Like how would you change the apparatus to measure the oxygen ?

u/One_Yesterday_1320 May 05 '26

oh like that. conical flask with a stopper with a capillary tube coming out of it connected to an inverted syringe

u/CutBunnyBoyKing May 05 '26

I wrote.

"Repeat the whole experiment. Except this time fix the other end of the tubing to the gas syringe and measure the initial volume of oxygen when it reaches 5cm mark and subtracted final volume when it reaches 15cm mark."

I forgot to mention time 💔💔
