Molar mass refers to the mass expressed in grams of all the elements that compose a substance. It can be simply described as the mass of a molecule in one mole, thus its unit is usually expressed in grams per mole. Solving for the molar mass of a ...
The ideal Gas Law (or the general gas equation), represented by the equation PV = nRT, where P = pressure, V = volume, n = number of moles, R = universal gas constant and T = temperature, is a great tool for predicting the behavior of gases under ideal conditions. From this, w...
Ordinary Portland cement (OPC) contributes significantly to the global CO2 emissions: in 2016, the estimated value was 1.45 ± 0.20 Gt CO2, that is, approximately 8% of the total anthropogenic CO2 release [1]. Although the cement industry has been able to improve energy efficiency significantly...
Finally, add together the total mass of each element to get the molar mass of C10H8O: 120.107 g/mol + 8.06352 g/mol + 15.9994 g/mol =144.16992 g/mol 5. Find Mole Fraction To find the mole fraction and percentage of each element in C10H8O, divide each total from step 3 by the ...
