This will vary by isotope of the element (carbon-12 vs. Mass of the sample is the weighted arithmetic mean of the masses of the individual atoms present in the sample (also The relative atomic mass of a compound is the ratio of the average mass of the elements in a chemical compound to theĪtomic mass constant, which is defined as 1/12 the mass of a carbon 12 atom. What Is Relative Atomic Mass / Relative Molecular Mass / Average Molecular Weight? By converting the atomic interaction into grams, we can measure and use an appropriate amount of the necessary reagents. To make a given quantity of water? Molar mass allows us to convert a chemical reaction into specific amounts of reagents required for the Set up the materials in the laboratory? Or if you were, for example, buying oxygen for a process, how would you determine how much to use We may be able to balance a chemical equationĪnd determine that one molecule of hydrogen combines with two of oxygen to make water (or the compound of your choice). Molar mass is an important concept in adapting chemical formulas to real world conditions. Then copy and save the url.įAQ - Molar Mass Calculator What is Molar Mass in Chemistry? You also have the option of saving links to the calculations in your research notes files, so you can quickly re-open or check them later.Īgain - hit calculate first so the URL is updated with your most recent changes.

Our molar mass calculator has this for a variety of other compounds: sodium chloride,Ĭarbon dioxide, sulfuric acid, glucose. For example:įinding Molar Mass for Other Chemical Compounds Simply take each element and multiple it by the number of times the bracketed structure occurs. We don't have brackets implemented (yet), so you will need to unpack any bracketed expressions. It solves for total mass of a molecular formula (average molecular weight).įrom there we break the formula for Ammonia into parts. The molar mass calculator - it will show the count of atoms, the atomic weight of each element, and the molecular weight for the molecule. We present the results in a table at the bottom of Then weĬompare each atom against a table of the standard atomic weights for that element. We take the formula you provide (NaCl - common table salt - in our default example) and unpack it into the component elements. Other terms: atomic mass of Ammonia, molar mass of Ammonia, molecular mass, Use the mole ratio and empirical formula to understand the limits of the reactants. Percent yield calculator which can help you apply this to actual experiments. This project started with as a molar mass calculator for chemical reactions. Note that the calculator assumes a pure substance - if you'reĪware of dilution or impurities, make appropriate adjustments for the molarity of a given substance. The calculator takes the elemental composition of the compound and weighs the elements to get an The molar mass of a chemical compound based on the compound's empirical formula. Need to know the atomic mass of a Ammonia molecule? Our molar mass calculator uses the periodic table and the chemical formula to solve for
