This is one of those (horrors!) Stoichiometry problems.
1. What is the Atomic Weight of Silicon
2. How many Moles of Silicon in 1 pound
3. Multiply Moles by Avogadros Number to get Number of Atoms.
As always, math is left as an exercise for the student.

How many silicon atoms are there in 1 cm3 of material?
2.5x10^22 atoms
How many moles is 2.80x1024 atoms in silicon?
2.80x10^24 atoms x 1 mol/6.02x10^23 atoms = 4.65 moles
How many atoms of silicon are in 1.43240 moles?
1 mole of an element contains 6.022 X 1023 atomsso in 1.4324 moles no. of atoms is 8.659 X 1023 atoms
What is the number of atoms in one unit of the compound silicon dioxide?
Well take Si (as its own element, being silicon) and see how many atoms it has in that one unit, which would be 1 (notice that it has no number next to it) then see how many atoms are in the O2 (Oxygen) obviously it has 2 because of the number next to it. So you take the two numbers and add. 2+1=3. 3 atoms are present.
What is the name of the shape that is formed when 4 oxygen atoms surround and bond with 1 silicon atom?
A silicon-oxygen tetrahedron.
1 a how many silicon atoms in each unit cell b.how many silicon atoms are there in one cubic centimeter.?
18
How many silicon atoms are there in 1 cm3 of material?
2.5x10^22 atoms
How many ATOMS of silicon are present in 3.10 moles of silicon dioxide?
3.10 moles SiO2 (1 mole Si/1 mole SiO2)(6.022 X 1023/1 mole Si) = 1.87 X 1024 atoms of silicon =====================
How many moles is 280X1024 atoms of silicon?
2.80x10^24 atoms x 1 mole/6.022x10^23 atoms = .465x10^1 mole = 4.65
How many moles is 2.80x1024 atoms in silicon?
2.80x10^24 atoms x 1 mol/6.02x10^23 atoms = 4.65 moles
How many elements are in SiO?
SiO2 is a macromolecule. Each silicon atom is covalently bonded to four oxygen atoms and each oxygen atom is covalently bonded to two silicon atoms.
How many ounces are in a pound of silicon?
1 pound of anything except precious metals or stones contains 16 ounces of the same stuff.
Is silicon dioxide a pure element?
No, a silicon dioxide molecule is composed of 1 silicon atom and 2 oxygen atoms.
How many atoms of silicon are in 1.43240 moles?
1 mole of an element contains 6.022 X 1023 atomsso in 1.4324 moles no. of atoms is 8.659 X 1023 atoms
How many atoms of oxygen are in 0.100 moles of silicon dioxide?
0.100 moles silicon (SiO2 ) dioxide (2 mole O/1 mole Si)(6.022 X 1023/1 mole O) = 1.20 X 1023 atoms of oxygen ======================
How many atoms are in four moles of silicon?
A mole of silicon (or any other element, for that matter) contains 6.02 x 1023 atoms. A mole of any compound contains that same amount of molecules. That big number is Avogadro's number, and more can be found by using the links below.
How many silicon atoms are there in 1.00 g of silicon?
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
