**Stoichiometry Problem: Preparing Chlorine in the Laboratory**Chlorine can be prepared in the laboratory by the reaction of manganese dioxide (\( \text{MnO}_2 \)) with hydrochloric acid (\( \text{HCl(aq)} \)), as described by the chemical equation:\[ \text{MnO}_2(s) + 4 \text{HCl(aq)} \rightarrow \text{MnCl}_2(aq) + 2 \text{H}_2\text{O}(l) + \text{Cl}_2(g) \]**Problem:** How much \( \text{MnO}_2(s) \) should be added to excess \( \text{HCl(aq)} \) to obtain 105 mL of \( \text{Cl}_2(g) \) at 25 °C and 715 Torr?**Hint:** It's another stoichiometry problem. See hints for previous problems. You will first determine \( n \), which represents moles of chlorine gas. Then, use stoichiometry to calculate moles of the reactant needed. Finally, convert this to grams of that reactant.**Calculation:** \[ \text{Mass:} \ \_\_\_\_\_\_\ \text{g MnO}_2 \]

You are carrying out an experiment to determine the MW of a solid acid with the generic formula H3A. You weigh out 0.362 g of the solid acid in a weigh boat and transfer it to a 125 mL Erlenmeyer flask. After dissolving the acid in 25 mL of distilled water, you add 22.51 mL of 0.343 M Sr(OH)2 (aq) solution with a buret until your indicator changes color at the equivalence point. What is the molar mass of the solid acid in units of g/mole? Enter your answer with at least 4 significant digits (Canvas sometimes truncates zeros so assume that all numbers in this question have at least 4 sig figs (ie if Canvas tells you there are 12.3 mL assume 12.30 mL). This question will require precision so don't round any numbers until your final answer.
