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? 9.41x10^-1 atm Using the data collected (in the previous problem), calculate the moles of hydrogen collected. 3.63x10^-3 mol Upon electrolysis, the metal is oxidized to a 2+ valence state. Based on this information, how many moles of metal are present? 3.63x10^-3 mol Use the mass of metal lost and moles from the previous problem to determine the atomic mass of the metal. ANSWER______X10^__ unit____ Based on the calculations performed in this question, select the identity of the unknown metal. COPPER, IRON, ZINC, OR NICKEL
