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 Weight/Volume Percentage is a measure of the concentration of a solution. 2  weight/volume percentage concentration is usually abbreviated as w/v 3  (%). w/v (%) = mass solute &divide volume solution x 100. 4  common units are g/100mL 5  (%). weight/volume is a useful concentration measure when dispensing reagents. weight/volume percentage concentration is usually abbreviated as w/v 2  (%). w/v (%) = mass solute &divide volume solution x 100. 3  common units are g/100mL 4  (%). weight/volume is a useful concentration measure when dispensing reagents.
