That’s right! Wet cotton is necessary for the gas trap to be effective.

Now you're ready to measure out the necessary reagents. Write down the quantities in your lab notebook.

benzyl cinnamate

photo shows a piece of weighing paper folded in half on top of a laboratory scale; the contents of the weighing paper are not visible; a small brown glass reagent bottle labeled “Benzyl Cinnamate” sits next to the scale; the scale reads “0.152 g”

10% Pd/C

photo shows a piece of weighing paper folded in half on top of a laboratory scale; in the fold of the weighing paper is small pile of black powder; a dark brown glass reagent bottle labeled “10% Palladium on Carbon” sits next to the scale; the scale reads “0.1032 g”

methanol

photo shows a large brown glass reagent bottle labeled “methanol;” the spigot of a fixed-volume bottle top dispenser is visible, and a gloved hand holds a 1-dram vial that is approximately half full with clear liquid
