WebCalculate the molar mass of the acid. A 6.50-g sample of a diprotic acid requires 137.5 mL of a 0.750 M NaOH solution for complete neutralization. Determine the molar mass of the acid. A 3.555 gram sample of a monoprotic acid was dissolved in water. It took 23.32 mL of a 0.875 M NaOH to neutralize the acid. Calculate the molar mass of the acid. WebThis was then multiplied by the % of ethyl acetate in the sample (45%) to calculate the molar mass of ethyl acetate in the sample. This resulted in 39.955 g/mol. Next, the mass of ethyl acetate in the sample was calculated by multiplying the molar mass by the total mass of the sample (1.018 g).
WebJul 8, 2016 · H has an atomic weight of 1.008 g/mol. O has an atomic wight of 16.00 g/mol. Based on the chemical formula, we have 3 atoms of carbon so you would multiply the atomic weight of C by 3 to obtain 36.03 g/mol. You do the same for hydrogen, we have 6 atoms of H so you multiply the atomic weight of H by 6 to get 6.048 g/mol. WebEnter a chemical formula to calculate its molar mass and elemental composition: Molar mass of H is 1.007940 ± 0.000070 g/mol. Convert between H weight and moles. …
WebThe molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance's molar mass by summing the molar masses … WebJan 31, 2024 · To calculate this result: Calculate the molar mass of water, which is two hydrogen atoms' and one oxygen atom's molar masses combined: (2 × 1.008 g/mol) + 15.999 g/mol = 18.015 g/mol. Divide the mass of your sample by the molar mass: 100 g / 18.015 g/mol = 5.551 mol. This is the number of moles in 100 g of water.
