This worked example problem shows how to convert the number of grams of a molecule to the number of moles of the molecule. This type of conversion problem mainly arises when you are given or must measure the mass of a sample in grams and then need to work a ratio or balanced equation problem that requires moles. Determine the number of moles of CO 2 in grams of CO 2. First, look up the atomic masses for carbon and oxygen from the periodic table. The atomic mass of C is The formula mass of CO 2 is:. Thus, one mole of CO 2 weighs

How to convert grams to moles

The calculator below calculates the mass of the substance in grams or the quantity of the substance in moles. Depending on the input data it can serve either as grams to moles calculator or as moles to grams calculator. It also displays the molar mass of the chemical substance and details of its calculation just for reference. You can find more information and formulas about grams to moles conversion as well as about moles to grams conversion below the calculator. Note: Always use the upper case for the first character in the element name and the lower case for the second character as in the periodic table. Compare: Co - cobalt and CO - carbon monoxide. You need to divide the mass of the substance by the molar mass of the substance:. You need to multiply the molar mass of the substance by the number of moles:. As you can see, the most difficult task here is finding out the molar mass of the substance. The molar mass is a physical property defined as the mass of a given substance chemical element or chemical compound divided by the amount of substance. The molar mass of a compound is given by the sum of the standard atomic weight namely, the standard relative atomic mass of the atoms which form the compound multiplied by the molar mass constant. Multiplying by the molar mass constant ensures that the calculation is dimensionally correct: standard relative atomic masses are dimensionless quantities i. All you need to do is correctly enter your formula, choose whether you want a conversion from grams to moles or a conversion from moles to grams, and, in case of g to mol, enter the mass, or, in case of mol to g, enter the moles. Find out the molar mass of the substance hint: you can use Molar mass of the substance alone to calculate molar mass.
