How to convert grams to moles

To convert the grams to moles, we need to know the molar mass of the substance. To calculate it we are always going to need a periodic table. So, how do we find the molar mass in the periodic table? For example, there are two numbers given for potassium in the periodic table: 19 and The smaller one is the atomic number which shows the number of protons, and the larger one is the average atomic mass:. For potassium then, it is And we can do this for all the elements in the periodic table. To calculate the moles from a given mass m , the molar mass of the component is used.
