Example: You analyze a compound and find that it contains 0.675 g of hydrogen (H), 10.8 g of oxygen (O) and 13.5 g of calcium (Ca). What is the empirical formula?1. Find the Number of Moles of Each Element The molar mass of hydrogen is 1 g (rounding to one decimal place), so...
the mole fraction of the solvent = moles of solvent / total moles. Besides, in some cases, the mole number is not given directly. So, you have to find it using the chemical formula of the compounds their weight or their volumes.
