The number of moles represents the fraction: mass of the compound / molecular weight of the compound. This quantity is known as the molar mass, a term that is often used in place of the terms atomic weight or molecular weight. It lets you calculate the molar mass of up to 9 elements/compounds at a time. Ryznar Stability index. Langelier index calculator. isotopic composition of the elements. Tools: Formula Weight Calculator: Putting in a molecular formula of any type such as K2Cr2O7, CH3CH2COOH, KFe[Fe(CN)6]3, or Na2B4O7.10H20 will result in the molar mass and mass analyses being calculated when the button is pressed. It is calculated as the sum of the atomic masses of each constituent element or group of elements multiplied by the number of it in the molecular formula. When calculating the molecular mass, individual isotopes are considered separately. Calculations are based on the isotopic composition of the elements. If we add the mass unit (g) after the molecular weight number, it becomes the mass value of the material corresponding to 1 mole of the molecule. Knowing that the solution is 70 wt % would then allow the number of grams of HNO 3 to be calculated: (0.700)(1413g) = 989.1 grams HNO 3 per liter.
