How to Do Solution Stoichiometry Using Molarity as a Conversion Factor | How to Pass Chemistry

PRACTICE PROBLEM: A 34.53 mL sample of H2SO4 reacts with 27.86 mL of 0.08964 M NaOH solution. Calculate the molarity of the H2SO4 solution. H2SO4 + 2NaOH = Na2SO4 + 2H2O 📗 FREE CHEMISTRY SURVIVAL GUIDE https://melissa.help/freechemguide 💯 HERE'S HOW TO PASS ORGANIC CHEMISTRY 🎉 https://chemmunity.info/youtube 👉 MORE CHEMISTRY RESOURCES I CREATED 👈 https://melissamaribel.com/ 🎓 CHECKOUT MY COMPLETE CHEMISTRY GUIDES: 📕 Thermochemistry Guide https://melissa.help/thermonotes 📗 Acids and Bases Guide https://melissa.help/acidbase1notes 📘 Naming Compounds and Acids Guide https://melissa.help/namingnotes 📙 Dimensional Analysis, Significant Figures, and Density Guide https://melissa.help/sigfignotes 📕 Gas Laws Guide https://melissa.help/gaslawsnotes 📗 Stoichiometry Guide https://melissa.help/stoichnotes 📘 Redox Reactions Guide https://melissa.help/redoxnotes 📙 Molarity Guide https://melissa.help/molaritynotes 📕 Limiting Reactants Guide https://melissa.help/limreactnotes 📗 Lewis Structures Guide https://melissa.help/lewisnotes 📘 Kinetics Guide https://melissa.help/kineticsnotes 📙 Titrations Guide https://melissa.help/titrations 📕 Matter, Atomic Structure, Empirical and Molecular Formulas Guide https://melissa.help/matterguide 🙌 This was my go-to homework help when I was in school. Chegg Study is one of my favorites. https://melissa.help/cheggstudy 📚 I made the mistake of buying all of my textbooks, I wish I had the option of renting them. Thankfully you do, with Chegg Textbook Rentals. https://melissa.help/cheggbooks 💁‍♀️ HI I'M MELISSA MARIBEL I help students pass Chemistry and Organic Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING! DISCLAIMER: Some links in the description are affiliate links, which means that if you buy from those links, I’ll receive a small commission.

STEP BY STEP ANSWER: Given: 34.53 mL H2SO4 27.86 mL NaOH 0.08964 M NaOH Find: M H2SO4 Remember 0.08964 M NaOH means 0.08964 mol NaOH/ 1 L Step 1: Find mol of H2SO4 Plan: mL NaOH to L NaOH to mol NaOH to mol H2SO4 Metric system molarity NaOH mol to mol ratio Setup: 27.86 mL NaOH x ( 10^-3 L NaOH/ 1 mL NaOH) x (0.08964 mol NaOH/ 1 L NaOH) x ( 1 mol H2SO4/2 mol NaOH) = 0.001249 mol H2SO4 Step 2: Convert mL to L of H2SO4 34.53 mL H2SO4 x ( 10^-3 L H2SO4/ 1 mL H2SO4) = 0.03453 L H2SO4 Step 3: Divide mol/L M= 0.001249 mol H2SO4/0.03453 L H2SO4 Answer= 0.03617 M H2SO4
