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.
This information is used to calculate the empirical formula for a compound. The empirical formula is the simplest whole number ratio of atoms in a molecule. Example: Chemical analysis of a liquid shows that it is 60.0% Carbon, 13.4% Hydrogen, and 26.6% Oxygen by mass. Calculate the empirical formula of the substance.or example, if you have 0.50 moles of carbon atoms, how many atoms is that? 6.02 x 1023 atoms Carbon. 0.50 mol Carbon X -------------------------------------- = 3.01 x 1023 atoms Carbon. 1 mol Carbon. You can also convert from atoms to moles.
