Normality & Molarity Calculator Dividing the grams of HNO3 by the molecular weight of HNO3 (63.01 g/mole) gives the number of moles of HNO3 / L or Molarity, which is 15.7 M. The Molarity Calculator Equation: The following equation is used for calculating Molarity where the concentration is given in wt %: [(% x d) / MW] x 10 = Molarity. Where: % = Weight %; d = Density (or specific gravity); MW = Molecular Weight (or Formula Weight). The above equation can then be used to calculate the Molarity of the 70 wt % Nitric Acid:

One mole of Nacl is how many grams and how? 1 mole of NaCl is 58.5g. Mole = Mass/RMM. Ar for Na=23 & Ar for Cl = 35.5. Therefore 1mole = Mass / (35.5+23). 1 mole of NaCl is 58.5g. But that can be misleading. NaCl does not form into molecules (and salts in general do not). If you dissolve 58.5g of NaCl into water, it will dissociate into ions, and there will be 2 moles of particles in solution: 1 mole of Na+ ions, and 1 mole of Cl-ions.

How to Calculate Molar Mass Ask me questions on Facebook: http://www.facebook.com/chemistNATE. How to Calculate the Molar Mass of elements and molecules. Elements: Easy, just look at the periodic table. Molecules: Add up the masses of the atoms that form the compound. For example, an oxygen atom weighs 16.00 g/mol according to the periodic table.So an O2 molecule would weigh 2 x 16.00 g/mol = 32.00 g/mol.ow to Calculate the Molar Mass of elements and molecules.

How do you calculate a molecular formula given a compound's molar mass and empirical formula? Say you know the empirical formula is CH2O and the molar mass is 180 g/mol. We know the molecular formula is Cx H 2x O x. So we can write down an equation expressing the molar mass as a function of x: 12 * x + 1.01 * 2x + 16 * x = 180. --> x = 6. --> C6H12O6.
