A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 316.mg of oxalic acid H2C2O4 , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250.mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 93.2mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Be sure your answer has the correct number of significant digits.
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.
One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: Fe (s) + CuSO4 (aq) → Cu (s) + FeSO4 (aq)Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. He adds powdered iron to a 200.mL copper(II) sulfate sample from the plant until no more copper will precipitate. He then washes, dries, and weighs the precipitate, and finds that it has a mass of 73.mg . Calculate the original concentration of copper(II) sulfate in the sample. Be sure your answer has the correct number of significant digits.

The zinc content of a 1.55 g ore sample was determined by dissolving the ore in HCl, which reacts with the zinc. The excess HCl is then neutralized with with NaOH. The reaction of HClHCl with Zn is shown. Zn(s)+2HCl(aq)⟶ZnCl2⁢(aq)+H2⁡(g) The ore was dissolved in 150 mL of 0.600 M HCl and the resulting solution was diluted to a total volume of 300 mL. A 20.0 mL aliquot of the final solution required 8.92 mL of 0.548 NaOH to neutralize the excess HCl. What is the mass percentage (%w/w) of Zn in the ore sample?
