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.
Solution: : Finding the empirical and molecular formula is basically the reverse process used to calculate mass percent. Step 1: Find the number of moles of each element in a sample of the molecule. Our molecule contains 40.00% carbon, 6.72% hydrogen and 53.28% oxygen.This means a 100 gram sample contains:inding the empirical and molecular formula is basically the reverse process used to calculate mass percent.
