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.
From there, you calculate the ratios of different types of atoms in the compound. You express these ratios as the empirical formula. An empirical formula represents the lowest whole-number ratio of elements [â¦]
