Please, I need the answer for all questions. In the electrolysis experiment similar to the one employed in this experiment; a student observed that his unknown metal anode lost 0.238 grams while a total volume of 94.50 mL of hydrogen was being produced. The temperature of the solution was 25 °C and the barometric pressure was 740 mm Hg. The vapor pressure of water at 25 °C is 23.8 mm Hg. 1. What is the pressure of the hydrogen gas...

F. Would your value for "R" in the last experiment have been higher, lower, or the same if: a) all the magnesium had not reacted. b) we did not account for water vapor pressure. c) we did not account for the water level difference. d) the hydrogen was actually hotter than the water bath. The procedure of this experiment is based on the chemical reaction between magnesium metal and hydrochloric acid to produce hydrogen gas. Mg + 2 HCI -...

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!!
