Need help filling in my data sheet from a lab. My professor said the pressure was 24.6 inches of Hg and that we needed to convert that to moles. Im not sure i put that in the correct spot. I included the lab protocol. Plz plz plz help me fill in the blanks and let me know if i did something wrong Im very confused haha. THANKS!! Equivalent Mass by Electrolysis If the two terminals on any source of DC...
