Molar Mass (g/mol) Mg(Magnesium)1 × 24.305 = 24.305 Cl(Chlorine)2 × 35.453 = 70.906 H(Hydrogen)2 × 1.00794 = 2.01588 O(Oxygen)1 × 15.9994 = 15.9994 4. Sum Each Element's Mass Finally, add together the total mass of each element to get the molar mass of MgCl2(H2O): ...
There are 4 easy steps to find the molar mass of MgCl2{-} based on its chemical formula. 1. Count The Number of Each Atom The first step to finding the molar mass is to count the number of each atom present in a single molecule using the chemical formula, MgCl2{-}: ...
MgCl2 Molar Mass: One characteristic or feature of a molecule is the molar mass. It can be determined based on the chemical formula of the molecule. Basically, the molar mass of a molecule is equal to the sum of the molar mass of each element involved. One way to use the molar mass ...
In this case you would need to add the molar mass of magnesium and two times the molar mass of chlorine: Mg(24.305)+Cl(35.45×2)=95.211g/mol So the molar mass of MgCl2 is 95.211 g/mol. Using Molar Mass Now, you can tackle the question at the beginning of the article. Say you ne...
