15. You have 15 mL of a 0.25 M NaCl(aq) solution. What volume should you dilute it to in order to obtain a concentration of 0.15 M? 16. a. 12.5 g H₂ reacts according to the following equation in an excess of O₂. What is the highest possible mass of H₂O that can be produced? (Molar mass: H₂=2.02 g/mol; O₂=32.00 g/mol; H₂O=18.02 g/mol) 2 H₂(g) + O₂(g) → 2 H₂O(g) b. If only 89.3 g H₂O is collected, what was the percent yield? 17. What is the theoretical yield when 38.2 g Al reacts with 14.8 g O₂ according to the following reaction? (Molar mass: Al=26.98 g/mol; O₂-32.00 g/mol; Al₂O3=101.96 g/mol) 4 Al(s) + 3 O₂(g) → 2 Al2O3(s)
