How many silicon atoms are there in 85.0 micrograms of silicon?

To find the number of silicon atoms in 85.0 micrograms of silicon, you would first calculate the moles of silicon using its molar mass. Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.


How many silicon atoms are in 0.532 moles of silicon?

Multiply by avagadro's number (6.022x1023) giving 3.203704x1023 atoms


How many Si atoms in 12.5 g sample 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 12.5 gram of silicon?In 1 mol silicon (28.0855 grams) = 28.0855/28.0855 x 6.02214179 x 1023 = 6.02214179 x 1023 atomsIn 12.5 gram silicon = 12.5/28.0855 x 6.02214179 x 1023 = 2.680271755 x 1023 atomsRead more: How_many_silicon_atoms_are_there_in_1.00_g_of_silicon


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.


How many atoms of silicon are contained in 8.5 x 10-5gm?

To calculate the number of silicon atoms in 8.5 x 10^-5 grams of silicon, you would first determine the molar mass of silicon (28.09 g/mol) and then use Avogadro's number (6.022 x 10^23 atoms/mol) to convert grams to atoms. In this case, there are approximately 1.29 x 10^16 atoms of silicon in 8.5 x 10^-5 grams.

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.
