The empirical formula for any compound can be determined in a few easy steps. The procedure involves finding the amount of each element in the compound and converting that amount to moles, followed by individual mole ratio calculations. Once the individual mole ratios are calculated, the ratios c...
using the molar mass from the periodic table, convert the mass of each element to moles. divide each mole value by the smallest calculated number of moles. round to complete number nearest. this is the mole ratio of the elements, and is represented in the empirical formula by subscriptions....
To do this, divide the moles of magnesium by the moles of oxygen. Express the result to the correct number of significant figures. 6. Using the above ratio, write the empirical formula of magnesium oxide. Round off the ratio to the nearest whole number. 7. Using student results that have...
