Question: What is H 2 C 2 O 4 's molar mass? Molar mass of KHC2O4.H2C2O4 = 218.16012 g/mol Convert grams KHC2O4.H2C2O4 to moles or moles KHC2O4.H2C2O4 to grams. 1/2 * 0.0025 = approx 0.0012 mols H2C2O4.xH2O = grams/molar mass or molar mass = g/mol = approx 0.16/0.00125 = approx 128 for H2C2O4.xH2O. I got 15 g . ! Oxalic Acid. Convert mols NaOH to mols H2C2O4.xH2O. Before it dissolves, it's a white solid. Add up the atomic masses of the components of the compound. Get the detailed answer: Oxalic acid, H2C2O4*2H2O (molar mass = 126.07 g/mol) is often used as a primary standard for the standardization of a NaOH solutio Problem: Oxalic acid dihydrate, H2C2O4 * 2 H2O (molar mass = 126.07 g/mol) is often used as a primary standard for the standardization of an NaOH solution. Do a quick conversion: 1 moles H2C2O4 = 90.03488 gram using the molecular weight calculator and the molar mass of H2C2O4. If 0.147 g of oxalic acid dihydrate are neutralized by 23.64 mL of an NaOH solution, what is the molar concentration of the NaOH solution? 38/molar mass H2O = 38/18 = about 2 when rounded to a whole number so x must be 2. 2 Hydrogen = 2 2 Carbon = 24 4 Oxygen = 64 2 + 24 + 64 = 90 Thus, the molar mass of H2C2O4 is 90 grams per mole. Calculations: Formula: H2C2O4.2H2O Molar Mass: 126.0634 g/mol 1g=7.93251649566805E-03 mol Percent composition (by mass): Element Count Atom Mass %(by mass) Molar mass calculator computes molar mass, molecular weight and elemental composition of any given compound. Safety Data Sheet according to 29CFR1910/1200 and GHS Rev. The molar mass of oxalic acid dihydrate (H2C2O4-2H2O) H2C2O4 = 2 + (2 * 12) + (4 * 16) 2 H2O = 2 * 18 Molar mass = sum of the above=126 HOPE THIS HELPS!!! H 2 C 2 O 4 is known as oxalic acid when it's dissolved in water. + 1.00794*2 + 12.0107*2 + 15.9994*4 You know H2C2O4 is 90 so xH2O must be approx 128-90 = about 38. Calculate mass of oxalic acid (H2C2O4.2H2O) needed to prepare 250 ml ,1 M aqueous solution of oxalic acid . ››KHC2O4.H2C2O4 molecular weight. mass of 1 mol H2C2O4 = (2*1.008) + (2*12.01) + (4*16.00) = 2.016 + 24.02 + 64 = 90.04 g. mass of Carbon in 1 mol H2C2O4 = (2*12.01) = 24.02 g. mass percent of H2C2O4 … Is my answer correct ? Do a quick conversion: 1 grams H2C2O4 = 0.011106806606506 mole using the molecular weight calculator and the molar mass of H2C2O4.
