Report all answers with the proper number of significant figures. In an electrolysis experiment similar to the one employed 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 25oC and the barometric pressure was 739 mm Hg. The difference between the water levels in the beaker and buret was negligible. The vapor pressure of water at 25oC is 23.8 mm Hg. Based on the information provided and the lab handout, what pressure of hydrogen is collected, in atmospheres? Note: Your answer is assumed to be reduced to the highest power possible. Your Answer:__________x10 units_____ Using the data collected, calculate the moles of hydrogen collected. Your Answer:__________x10 units_____ Upon electrolysis, the metal is oxidized to a 2+ valence state. Based on this information, how many moles of metal are present? Your Answer:__________x10 units_____
