A Mg / Mg2+ // 2H+ / H2 galvanic cell generates a current of 2.15 x 10^-2 amperes for 205 minutes and in the process 29.9L mL of hydrogen at STP are collected. Calculate the values of Avogadro's number and the Faraday assuming the charge in an electron is 1.602 x 10^-19 coulombs/electron. Also calculate the mass the magnesium anode have lost during the process. The answers will be a number.
