bronchial tree, an anatomic complex of the trachea and bronchi. The bronchi branch from the trachea. The right bronchus is wider and shorter than the left bronchus and branches into three secondary bronchi, one passing to each of the three lobes of the right lung.. an anatomical structure with branches resembling a tree. 2. in information science, a decision tree. bronchial tree. the trachea, bronchi and successive branching generations of the respiratory passages.
The molecular formula for Silicon is Si. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Silicon, or 28.0855 grams. Note that rounding errors may occur, so always check the results.Use this page to learn how to convert between moles Silicon and gram.he molecular formula for Silicon is Si.

3.09%. Therefore, the atomic weight of silicon is. (27.977)(0.9221) + (28.976)(0.0470) + (29.974)(0.0309). = 28.086 amu. It is important to note that if we were to pick out a silicon atom at random and measure its mass, it would have a mass of either 27.977 amu, 28.976 amu or 29.974 amu, not 28.086 amu.owever, if you were to measure the masses of a billion silicon atoms (a quantity probably to tiny to see with the naked eye) individually and calculate the average mass you would find the average mass of a silicon atom is 28.086 amu.
