How many atoms are in 2.50 moles of Si?
2,50 moles of silicon contain 15,055352142.10e23 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 =====================
Is there an SI unit for number of atoms?
No SI unit for no. of atoms. But there is a SI unit to measure the amount of any substance. It is moles and mole is a fixed quantity. Each mole represents a group of 6.022 x 1023 particles. These particles may be atoms or molecules.
How many atoms are there in 6.26 g Si?
.250 mole 7.02 ------ 28.09 = .250
How many moles are present in gram's of silicon Si?
1 g silicon is equal to 0,0356 moles.

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 atoms are there in 250 mol Si?
1 mole of anything is 6.022 x 1023 atoms or molecules of that substance. Thus, 2500 atoms of a substance is about 4.151 x 10-21 moles of that substance.
How many moles of silicon are in 245 g of silicon?
1 mole Si = 28.0855g Si 245g Si x 1mol Si/28.0855g Si = 8.72 moles Si

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 there in 6.26 g Si?
.250 mole 7.02 ------ 28.09 = .250
How many moles are present in gram's of silicon Si?
1 g silicon is equal to 0,0356 moles.
How many atoms of Si are in H4SiO4?
In a molecule of H4SiO4 only one Si atom is present
How many moles are present in gallon's of silicon Si?
Gallon is a unit for liquids.
How many atoms of Si are in 237 g of Si?
237g / 28 gmol-1 = 8.46mol. 8.46 x (6.02x1023) = 5.09x1024 silicon atoms.
SI unit for amount?
