Calculate Compound Composition for Portland Cement with Oxide Analysis

Calculation of Compound Composition for Portland Cement

To calculate the compound composition for a Portland cement with a given oxide analysis, the following steps need to be followed:

Step 1: Convert the percentage of each oxide into grams. For example, if we have 100g of the compound, we would have 40g of carbon, 6.7g of hydrogen, and 53.3g of oxygen.

Step 2: Convert the grams of each element to moles using the molar mass of each element. The molar masses are: C (carbon) = 12.01 g/mol, H (hydrogen) = 1.01 g/mol, O (oxygen) = 16.00 g/mol.

Step 3: Divide each mole value by the smallest number of moles to find the empirical formula. In this case, calculate the moles for carbon, hydrogen, and oxygen, then find the smallest number of moles among them.

Step 4: Use the smallest number of moles to determine the empirical formula. In this case, the empirical formula for the Portland cement compound is approximately C3H8O2.

By following these steps, you can accurately calculate the compound composition for a Portland cement based on the oxide analysis provided.
