A mole is like a dozen. It is a name for a specific number of things. There are 12 things in a dozen, and 602 hexillion things in a mole. We'll talk about what moles are and why they are important. We will see how to abbreviate the mole number (Avogadro's number) using scientific notation, and we'll see how giant this number is.
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://sellfy.com/p/NbUf/ 👉 SHOP MY STEP-BY-STEP CHEMISTRY NOTES👈 https://sellfy.com/melissamaribel Thermochemistry: https://sellfy.com/p/9zWI/ Acids and Bases: https://sellfy.com/p/Ta1z/ Naming Compounds and Acids: https://sellfy.com/p/Cpof/ Dimensional Analysis, Significant Figures, and Density: https://sellfy.com/p/6AnT/ Gas Laws: https://sellfy.com/p/De81/ Stoichiometry: https://sellfy.com/p/NObu/ Redox Reactions: https://sellfy.com/p/rQsZ/ Molarity: https://sellfy.com/p/2A3h/ Limiting Reactants: https://sellfy.com/p/J2oT/ Lewis Structures: https://sellfy.com/p/HjLq/ 🧡SHOW YOUR SUPPORT ON PATREON https://www.patreon.com/melissamaribel 👍MELISSA'S FAVORITES ON AMAZON https://www.amazon.com/shop/chemistrywithmelissamaribel --OTHER RESOURCES TO HELP YOU GET THROUGH SCHOOL-- 🙌 This was my go-to homework help when I was in school.
