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.
1 finding the ratios of elements in a compound gives the empirical formula (from percentage composition) 2  C6H12O2 (molecular formula) >> CH2O (empirical formula)  subscripts in the molecular formula can be found by multiplying the subscripts in the empirical formula by a whole number.
