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.
How to calculate a value from the percentage part, a ratio (Y/P% = X): Calculator 3a is a word problem version of the equation Y/P% = X in 3b so they are solved the same way. For example, how to solve for a value when you know what a percentage part is:alculator 1a is a word problem version of the equation P% * X = Y in 1b so they are solved the same way. For example, how to solve for the percentage of a number: 1  What is 10% of 150? in equation form is 10% * 150 = Y. 2  We need to first convert the percentage to an equivalent decimal to do our calculation.
