Mole is the standard unit of amount measurement. Substances react in simple ratios of moles. But, when you have to compare the amount of one substance to another by moles, you must convert into grams since balances do not provide readings in moles. Show
You have three steps to convert mole values to grams.
One mole consists of Avogadro number of atoms. If you know the quantity of mole, it can be converted into grams and vice versa. The formula for moles to grams is given by Example 1 –Calculate the mass in grams of 3.6 mol of H2SO4. Solution Look for the atomic masses of hydrogen, sulfur and oxygen. H = 1.008 S = 32.06 O = 16 Therefore, the molecular mass of H2SO4 is 2(1.008) + 32.06 + 4(18) = 106.076 Hence, one mole of H2SO4 weights 106.076 grams. Since you need to find for 3.60 mol of H2SO4 = 3.60 mol x 106.076 g/mol = 381.87 g of H2SO4 Example 2. Convert 3 moles of carbon monoxide to grams. Solution Find the molecular weight of Carbon monoxide. By calculating, we get the molecular weight of CO = 28.01 g/mol Since we need to find for 3 moles of Carbon monoxide = 3 x 28.01 = 84.03 grams ›› More information from the unit converterHow many moles In in 1 grams?

Finding molar mass starts with units of grams per mole (g/mol). 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. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. 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. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. 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. ›› Metric conversions and moreConvertUnits.com provides an online conversion calculator for all types of measurement units. 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, 100 kg, US fluid ounce, 6'3", 10 stone 4, cubic cm, metres squared, grams, moles, feet per second, and many more! Is 1 gram the same as 1 mole?Thus the mass of 1 mole of atoms of an element is equal to its gram atomic mass. Molecular mass of an element or a compound is equal to the sum of the atomic masses of each type of it's constituent atoms. Thus the mass of 1 mole of molecules of an element or a compound is equal to the gram molecular mass.
How do I convert grams to moles?Divide the number of grams of the compound, NaOH, by the molecular weight and as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).
