Silicon is a common metalloid which is a chemical element but it is considered to be tetravalent metalloid which has only 4 available electrons for covalent chemical bonding in its valence region. In the Periodic Table, Silicon has atomic number 14 with Si symbol. It is good to know that silicon is less reactive that Carbon-14 based on its position in the periodic table which is in the bottom of Carbon.
The Standard Atomic Weight for Silicon is 28.0855 grams. The standard is based on the Avogadro's Constant which is 6.02214179 x 1023 mol-1. 1 mol of silicon will contains 6.02214179 x 1023 atoms of silicon. So, how many atoms are present in 1 gram of silicon?
In 1 mol silicon (28.0855 grams) = 28.0855/28.0855 x 6.02214179 x 1023 = 6.02214179 x 1023 atoms
In 1 gram silicon = 1/28.0855 x 6.02214179 x 1023 = 2.144217404 x 1022 atoms

∙ 14y agoMolar mass is defined as mass of one mole of the substance. silicon molar mass is 28.09g/mol.
i.e when u weigh one mole of silicon atoms, u will be getting 28.09g. This molar mass concept will be very useful in calculations of concentration which needs the number of moles.

find mols of silicon in 1g = approx. 0.357 then times by RFM of silicon dioxide (60)
therefore:

How many silicon atoms are there in 85.0 micrograms of silicon?
n = (8.5 x 10^-5 g) x (1 mol / 28 g) = 3.04 x 10^-6 mol N = (3.04 X 10^-6 mol) x ((6.02 x 10^23 atoms)/(1 mol)) = 1.81 x 10^18 atoms
How many moles of phosphorus atoms are in a 100 g sample of phosphorus?
The gram atomic mass of phosphorus is 30.9738, and by definition, a mole of such atoms contains Avogadro's Number of atoms. Therefore, 100 g of phosphorus contains 100/30.9738 or 3.23 moles, to the justified number of significant digits.
How many grams of sand are needed to make 45 grams of silicon?
96,27 g of sand contain 45 g of silicon (if the sand is pure silicon dioxide).
Cost of silicon sheet?
Regular grade silicon (99%) costs about $0.50/g. Silicon 99.9% pure costs about $50/lb; hyperpure silicon may cost as much as $100/oz.
