Gram to molecule converter

There are two nitrogen atoms in one molecule of imidazole. Say you have 21 grams of imidazole. How many atoms of nitrogen are there in that 21 grams of imidazole? You will need the following conversion factors: molar mass She has an interest in astrobiology and manned spaceflight. She has over 10 years of biology research experience in academia. She currently teaches classes in biochemistry, biology, biophysics, astrobiology, as well as high school AP Biology and Chemistry test prep.

Given this information, you have a way to convert from mol to molecules. This means that in 21 grams of imidazole there are 3. Always remember to think about conversion factors and the units you want to end up with! How to Calculate Moles From Liters. How to Calculate Mmol. How to Determine Moles in Chemistry. And here is how you should enter this problem into the calculator above: grams to moles problem solution. The molar mass of KClO3 is And here is how you should enter this problem into the calculator above: moles to grams problem solution.

In many chemistry problems, you need to convert grams to moles or moles to grams. Convert moles to grams and grams to moles. Substance formula. Imagine you have 6 liters of pure water :. It's easier to work with grams, so convert the mass :. Knowing how to convert grams to moles may be helpful in numerous chemical tasks, e. Embed Share via. Table of contents: How to calculate moles from grams?

How to convert grams to moles: an example. How to calculate moles from grams? How to use g to mol calculator? The tool is really user friendly, and pretty straightforward to use: Pick one of the possible groups of compounds you can choose one from Common Gases and Liquids, Salts, Acids, Alkali, Organic, or Pure Metals. Input the mass of your substance.

And that's all! Our grams to moles calculator knows how to do its stuff! When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. 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.

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.
