1.03.3.1 Molar Mass Distribution Because of the stochastic nature of typical industrial polymerization processes, the molecular weight of the individual macromolecules that constitute a polymer may vary widely within a given batch and depend strongly on the reaction conditions. Therefore, one usually refe...

The Hill system (or Hill notation) is a standard way of writing the formula for any chemical compound. With the Hill notation, the number of carbon atoms in a molecule is indicated first, the number of hydrogen atoms next, and then the number of all other chemical elements subsequently, in...
A gaseous hydrocarbon contains 79.85 % carbon and 20.15 % hydrogen by mass. At the pressure of 760 mmHg and temperature of 25 °C, a 256mL sample of the gas was measured to have a mass of 0.315 g. Identify the molecular formula of the compound. ...
Molar Mass for Elements The mass in grams of one mole of substance is called molar mass. Each element has its own unique molar mass. For example, carbon’s molar mass is 12.011 g/mol, and magnesium’s molar mass is 24.3050 g/mol. To see why these elements have different molar masses...
