Calcium (Ca (s), MM = 40.078 g/mol) is prepared industrially from ionic liquids through the reaction:   Ca2+ (l) + 2 Cl– (l) → Ca (s) + Cl2 (g)   Calculate the mass (in g) of solid calcium produced by a constant current of 10.4 applied for 334. seconds.   F = 96500 C/mol   Report your answer to 3 significant figures without the unit. Example: 0.100

A 1.00-L solution of 4.7 × 10–6 M HCl is prepared. A 1.00-mL aliquot (i.e., sample) of this solution is transferred to a large container to which deionized water is added until the final volume is 1000.-L such that the final HCl concentration is 4.7 × 10–12 M. What is the pH of the final 1000.-L solution?   Report your answer to 2 decimal places. Example: 1.00
