Did you mean to find the molecular weight of one of these similar formulas? Atomic Mass: 58.933200 B. B. A. D. 2.0 10-3 mol/L C. 2.1 10^13 Step 1: Write the balanced chemical equation for the dissociation of CH3CO2H in water. A. AgCl Ag2CrO4 AgBr AgI 3.6 10-8 mol/L What mass of solid NaCH3CO2 (molar mass = 82.0 g/mol) should be added to 1.0 D. 0.1141 M C. 1.6 10-4 M Sodium Acetate NaCH3COO Molar Mass, Molecular Weight. 4.5 10-34 D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg ( ) [ ] D. 7.73 Question 6. 3.02 You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. What is the pH of a buffer that results when 0.50 mole of H3PO4 is mixed with 0.75 mole of NaOH and diluted with water to 1.00 L? B. D. 1.1 10-4 mol/L (Ka of benzoic acid = 6.3 10-5) 22.98977 + 12.0107 + 1.00794*3 + 58.9332*2, Element: Sodium CHEM 122 Final Exam Flashcards | Quizlet (pK. The Ksp of Mn(OH)2 is 1.9 10-13 at 25 C. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. Molar mass of CH3COONa = 82.03379 g/mol Convert grams Sodium Acetate to moles or moles Sodium Acetate to grams Molecular weight calculation: 12.0107 + 1.00794*3 + 12.0107 + 15.9994 + 15.9994 + 22.98977 Percent composition by element Element: Sodium Symbol: Na Atomic Mass: 22.989770 # of Atoms: 1 Mass Percent: 28.025% Element: Hydrogen Symbol: H # of Atoms: 2 Molar mass of NaCH3CO2(H2O)3 - WebQC 7.21).
