Capillaries are the smallest and most fragile of the body's blood vessels. They are responsible for what is known as microcirculation, meaning that they create a circulatory network within the organs of the body. There are three different types found in the human body: continuous, fenestrated, and sinusoidal.
1 Find the empirical formula. 2  Get the mass of each element by assuming a certain overall mass for the sample (100 g is a good mass to assume when working with percentages). 3  Convert the mass of each element to moles.  Find the ratio of the moles of each element.
Definitions and notation follow: 1  Let P = percentage solids by weight, 2  D = dilution, or ratio of weight of liquid to weight of solid, 3  S = specific gravity of solid,  W = weight of one liter of pulp in 1  grams, w = weight of dry ore (grams) in one liter of pulp,  K = the solids constant,
