How Do You Calculate The Number Of Moles In A Substance?
Having trouble with your mass to mole equations? I’m here to help. By following this simple step-by-step guide, you will be able to calculate the number of moles in any substance in a jiff. Draw a long horizontal line and a small vertical line cutting it in half. Write the mass of the substance from the problem in the top left section of your crosshairs. Get out a periodic table and find the mass of your substance. If your substance consists of only one element then you can continue to the next step. If your substance consists of more than one element then you must first add up the masses of all the elements in the substance before continuing on. Place this mass from the periodic table in the bottom right corner of the crosshairs. Now put “1 mol X” where X is the substance’s symbol in the top right corner. Finally we calculate number of moles. First multiply the values above the line, then divide by the values below the line. Example: How many moles are in 2.83 grams of Hydrogen? Put 2
