How Do You Calculate Moles To Grams In Chemistry?
In chemistry and chemical engineering, stoichiometry refers to the area of chemistry that deals with ratios of molecules involved in a given reaction. The “mole” unit is defined as 6.022 *10^23 molecules of a given substance. To calculate the weight of one mole of a particular molecule, you need to multiply the total number of molecules by the sum of all the atoms that comprise each particle (a.k.a. the molar mass). Step 1 Write down the substance’s molecular formula. For example, glucose’s molecular formula is C6H12O6. Step 2 Visit “zebu.uoregon.edu/~imamura/122/images/periodic_table.gif” to look up the Relative Atomic Mass for each atom in the molecule. In the case of glucose, you would find that carbon (C) has a Relative Atomic Mass of 12.011, hydrogen (H) has one of 1.0079 and oxygen has one of 15.999. Step 3 Multiply the Relative Atomic Mass of each atom by the number of atoms in the molecule. Since there are 6 carbon atoms in a glucose molecule, you would multiply 12.011 by 6. St
