9. a. What volume of a 17.4 mol/L acetic acid stock solution is required to make 2.0L of a 1.5 mol/L acetic acid solution? b. What is the pH of the initial solution if the [H*) concentration is 1.77 x 102 mol/L? c What is the pH of the diluted solution if the [H*] concentration is 5.2 x 107 mol/L? 10. If 74.5 g of ammonium nitrate was the actual amount obtained in a reaction for which the theoretical yield was 88.0 g, determine the percentage yield. 11. When 30.0 g of sodium hydroxide is mixed with excess magnesium nitrate according to the equation: Mg(NO3)2 + 2NaOH Mg(OH)2 + 2NaNO, a. Determine the theortetical yield of Mg(OH)2 b. Determine the percent yield of the reaction if 16.0 g of magnesium hydroxide is collected
