Question 7 4 pts Calculate the mass of Au in grams (to 2 sig figs) that can be plated in 28 min using 8.2 A for the half-reaction Au3+ (aq) + 3e Au(s) (assume that the molar mass for gold is 196.97-). if the answer is 2.1 g just type 2.1) mol

The Toyota Mirai is a hydrogen fuel cell car. It creates electrical energy through the reaction of hydrogen and oxygen to make water H2(g) + O2(g) + H2O(1) There is the following data Compound AH°: (kJ/mol) Sº (J/mol-K) H2 0 130.6 02 o 205.0 H2O -285.93 69.9 What is the value of AGº per mole of H2O made in this reaction in kJ/mol at 25.0°C. If the answer is-123.3 kJ/mol just type - 123.3 as Canvas won't understand the units
