4SiO2 means SiO2 + SiO2 + SiO2 + SiO2
The '4 'tells you that there are four seprate molecules of SiO2
So there will be 4 silicon atoms in 4SiO2
SiO2 also contains 2 oxygen atoms. So overall there will be 4 x 2 = 8 oxygen atoms.
SiO2 is silicon dioxide ; sand that you find on a beach.
It does form large crystal lattice by a loose combination through the oxygen atoms.

How many atoms make up 3.29 g of silicon?
To determine the number of silicon atoms in 3.29 g, you first need to calculate the number of moles of silicon using its molar mass (28.0855 g/mol). Then, use Avogadro's number (6.022 x 10^23) to convert moles to atoms.
How many moles is 2.80x1024 atoms in silicon?
To calculate the number of moles in 2.80x10^24 atoms of silicon, you first need to determine the molar mass of silicon, which is approximately 28.0855 g/mol. Next, you can use Avogadro's number, which is 6.022x10^23 atoms/mol, to convert atoms to moles. Divide the number of atoms by Avogadro's number to get the number of moles. Therefore, 2.80x10^24 atoms of silicon is equivalent to approximately 4.65 moles.
How many grams of silicon would there be in a sample that contained 9.99 x 1025 atoms?
To determine the grams of silicon in the sample, you need to know the molar mass of silicon. Since silicon's atomic mass is approximately 28 g/mol, you can calculate the grams of silicon by dividing the number of atoms by Avogadro's number and then multiplying by silicon's molar mass. This calculation would provide you with the amount of silicon in grams in the given sample.
How many atoms are in 15.6 g of silicon?
To find the number of atoms in 15.6 g of silicon, you would first calculate the moles of silicon using its molar mass (28.09 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. The final calculation would yield the number of atoms in 15.6 g of silicon.

How many moles of silicon do you have if you have 6.02 x 1024 atoms?
A mole of the element silicon is generally considered to have Avogadro's Number of atoms, since there is no particular small number of silicon atoms that is known to have distinct and persisting chemical bonds different from those of any other part of a sample of silicon. The number shown in the question is about 10 times Avogadro's Number and therefore contains ten moles.
Calculate the number of atoms in 0.543 mol of silicon?
The number of molecules in a mole is known as "Avogadro's Number" and is about 6.002 times ten to the twenty-third power. Therefore, the number of moles is 0.543 X 6.022 = 3.27 times ten to the twenty-third power. (This answer will be the same for moles of any substance.) Silicon is generally regarded as having only one atom per molecule, so that the number of atoms will be the same as the number of moles. Under certain conditions, however, silicon may occur as polyatomic molecules, and in such an instance the answer would be different.
