Question

the element silicon (si) is essential to the electronics industry. it is the active component of almost all microchips and solar energy panels. different forms of silicon are used depending upon the application, crystalline silicon for microchips to amorphous silicon for the last expensive solar panels. shown below are atomic - scale representations of three types of silicon. if you had exactly one mole of silicon in each of these three forms, which would weigh the most? crystalline silicon would weigh the most semi - crystalline silicon would weigh the most amorphous silicon would weigh the most they would all weigh the same dont test me yet, i am trying to gain an understanding before attempting to answer this question.

Explanation:

The molar mass of a substance is an inherent property. One - mole of any pure substance has the same number of atoms (Avogadro's number, \(6.022\times 10^{23}\)). Since all three forms (crystalline, semi - crystalline, and amorphous) are of silicon, and we are considering one mole of each, the number of silicon atoms is the same in each case. Mass is calculated as \(n\times M\) (where \(n = 1\) mole and \(M\) is the molar mass of silicon), so they have the same mass.

Answer:

They would all weigh the same
