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.
The empirical formula of a compound is also called the simplest formula. It. represents the relative or smallest whole-number ratio of atoms in a cmpd. 2. The molecular formula represents the actual number of atoms of each element. in a molecule of the compound. 3. The empirical formula and the molecular formula are mathematically related as. follows: Molecular formula = n x empirical formula.
