Watch concept videos about Limiting Reagent. Question How many moles of sodium bromide can be produced from the reaction of 1. We use the most common isotopes. This is how to calculate molar mass average molecular weight , which is based on isotropically weighted averages.
This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.
Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction.
These relative weights computed from the chemical equation are sometimes called equation weights. A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying to convert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass. You can find metric conversion tables for SI units, as well as English units, currency, and other data.
Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types.
Examples include mm, inch, kg, US fluid ounce, 6'3", 10 stone 4, cubic cm, metres squared, grams, moles, feet per second, and many more!
