What is the mass, in g, of Avogadro's number of phosphorus atoms? If 3 moles of an element have a mass of 222.0 g, what is the mass of 1 atom? What is the mass in grams of 3.011 times 10^{23} atoms of F? What is the mass of 1 mole of atoms of carbon? What is the...
Such methods are limited to low-molecular-weight polymers (several thousand grams per mole or less). This method has the drawback that it does not represent the behavior of polymer mixtures very well. Consider an extreme, hypothetical example; suppose during kraft pulping that 10 individual ...
