where x (g/mol) is the molar mass of the starting metal, 100% is the weight of the starting metal, 16 (g/mol) is the molecular weight or molar mass of oxygen, and y% is the weight gained by heating. For example, let us say we are starting with 100% of metal. That corresponds...

To find the molar mass of a compound, you need to add the molar mass of all the elements in that compound. Take a look at NaOH which contains sodium, oxygen and hydrogen. The molar mass of sodium is 22.99 g/mol, oxygen is 15.999 g/mol, and hydrogen is 1.008 g/mol. Adding them t...
Molar Mass (g/mol) Hg (Mercury) 1× 200.59 = 200.59 O (Oxygen) 1× 15.9994 = 15.9994 I (Iodine) 1× 126.90447 = 126.90447 4. Sum Each Element's Mass Finally, add together the total mass of each element to get the molar mass of HgO(I): 200.59 g/mol + 15.9994 g/mol + 126.9044...
aThe oxygen balance of an explosive is the mass of oxygen either in excess (i.e. the balance is positive) or in deficit (i.e. the balance is negative)of that required for complete oxidation of C and H. The oxygen balance is expressed as a percentage of the molar mass of the explosiv...
Apply the same principles to calculate the molar mass of a molecule. The molar mass of water is the mass of one mole of H2O. Add together the atomic masses of all of the atoms of hydrogen and water in amolecule of water: 2 x 1.008 g (hydrogen) + 1 x 16.00 g (oxygen) = 18.02 ...
For example, one molecule of nitric acid (HNO3) contains one nitrogen atom weighing 14.01 amu, one hydrogen atom weighing 1.008 amu, and three oxygen atoms weighing (3 × 16.00 amu) = 48.00 amu. The formula mass of nitric acid is therefore (14.01 amu + 1.008 amu + 48.00 amu) = 63.02...
