Molecular Weight Calculator. This online calculator you can use for computing the average molecular weight (MW) of molecules by entering the chemical formulas (for example C3H4OH(COOH)3 ). Or you can choose by one of the next two option-lists, which contains a series of common organic compounds (including their chemical formula) and all the ...


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.


Calculating formula masses. Since a molecule - scratch that, there we go again, calling everything molecules! Since a formula is made of atoms, we can calculate a formula mass by simply adding up all the atoms that are in it. This is an application of the law of conservation of mass.


Computing molecular weight (molecular mass) To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets. Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2. Definitions of molecular mass, molecular weight, molar mass and molar weight


A related term you should know is relative formula mass (relative formula weight). This simply means the calculation is performed using relative atomic weight values for the elements, which are based on the natural isotopic ratio of elements found in Earth's atmosphere and crust.

This program determines the molecular mass of a substance. Enter the molecular formula of the substance. It will calculate the total mass along with the elemental composition and mass of each element in the compound. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.


This web application calculates the molecular mass (average, monoisotopic, and nominal), the elemental composition, and the mass distribution spectrum of a molecule given by its chemical formula, relative element weights, or sequence. Calculations are based on the isotopic composition of the elements. Mass deficiency due to chemical bonding is ...


How to Calculate Mass. Mass means how much matter there is in something. Matter is something you can physically touch. Generally, mass is related to size but not always. A balloon might be bigger than something else but have less mass, for...


Ideal Weight Calculator. The Ideal Weight Calculator computes ideal bodyweight (IBW) ranges based on height, gender, and age. The idea of finding the IBW using a formula has been sought after by many experts for a long time. Currently, there persist several popular formulas, and our Ideal Weight Calculator provides their results for side-to-side comparisons.
