A rough analogy is when the oil in your car's engine is dirty and needs changing, it gets blackened, thick and sludgy. Thickened bile can't flow well. Since your intestines REQUIRE bile to stimulate movement, poor bile flow causes lack of peristalsis, which equals constipation.
A water molecule measure approximately 2.75 angstroms, making it one of the smallest of all molecules. One meter is 10 billion angstroms. The water molecule is shaped like a V, with two atoms of hydrogen extending at an angle of around 104 degrees from an atom of oxygen. Continue Reading.
So by simply taking the volume of the unit cell in cubic angstroms and dividing it by, say, 17 or 18 in your case, you can get an idea how many atoms are in the unit cell. Since there are 12 atoms in your formula, you should find some number that is close to a multiple of 12, which tells you how many formula units are in the cell. That's the easiest way. 4 Recommendations
