How many grams of silicon would there be in a sample that contained 9.99 x 1052 atoms?
To calculate the mass of silicon in the sample, you would first convert the number of atoms to moles using Avogadro's number. Then, you would calculate the mass of silicon in grams using the molar mass of silicon (28.0855 g/mol). The final mass would depend on the number of atoms in the sample.
What is the definition of the word silicon?
Silicon is a semi-metallic (or metaloid) element, with atomic number 14; it is found in many kinds of rock and minerals.
What is the description of silicon?
Silicon is a chemical element with symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre. It is a semiconductor, widely used in electronics and solar technology.
Is silicon a mixture or a solution?
First: a solution is a kind of mixture. Second: silicon is not any sort of mixture or solution. It is a pure element.
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.
What is the atomicity of silicon?
Atomicity, what a charming old word. Used to mean either valency or the number of atoms in a molecule. For silicon the valency is 4. (where valency was the numebr of bonds that could be formed) Silicon is not molecular, it is normally encountered as a solid with a network lattice.
How do you calculate how many protns are in silicon?
It is not something you calculate. The number of protons in an atom can be determined by looking up its atomic number on the periodic table. In the case of silicon, the atomic number is 14, so it has 14 protons.

1 a how many silicon atoms in each unit cell b.how many silicon atoms are there in one cubic centimeter.?
a. There are 8 silicon atoms in each unit cell of a silicon crystal in a diamond cubic structure. b. The density of silicon is 2.33 g/cm^3, and the molar mass of silicon is approximately 28.09 g/mol. By using Avogadro's number, you can calculate that there are approximately 5 x 10^22 silicon atoms in one cubic centimeter.
Is silicon a mixture or a solution?
First: a solution is a kind of mixture. Second: silicon is not any sort of mixture or solution. It is a pure element.
What is the atomic number of agate?
Agate is a type of chalcedony mineral composed of silicon dioxide. As a mineral, agate does not have an atomic number. Atomic numbers are assigned to elements in the periodic table based on the number of protons in their nucleus.
Is silicon an element or a compound or heterogeneous mixture or a homogeneous mixture?
is silicon a mixture? Silicon is a pure substance because it is an element.
What is the chemical composition of silicon?
Silicon is a chemical element with the symbol Si and atomic number 14. It is a crystalline solid with a silver-gray metallic luster. Its chemical composition consists of each atom containing 14 protons and 14 electrons.
How do you calculate the number of moles in 2.61 grams of silicon?
For this you need the atomic mass of Si. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.2.61 grams Si / (28.1 grams) = .0963 moles Si
Form of silicon?
Silicon exists in a crystalline solid form in nature, such as in the form of silicon dioxide (silica) which is found in quartz. It can also be produced synthetically in various forms including polycrystalline silicon used in solar panels, amorphous silicon used in electronics, and as silicon carbide which is a very hard material used in abrasives.
