1 g silicon is equal to 0,0356 moles.
2,50 moles of silicon contain 15,055352142.10e23 atoms.
The answer is 0,465 moles.
The conversion is impossible.It is difficult to use a dry gallon to measure silicon.
Gallon is a unit for liquids.
2,80 1024 atoms of silicon equals 0,465 moles.
1 g silicon is equal to 0,0356 moles.

2,50 moles of silicon contain 15,055352142.10e23 atoms.
The answer is 0,465 moles.
Multiply by avagadro's number (6.022x1023) giving 3.203704x1023 atoms
1 mole Si = 28.0855g Si 245g Si x 1mol Si/28.0855g Si = 8.72 moles Si
The conversion is impossible.It is difficult to use a dry gallon to measure silicon.

Gallon is a unit for liquids.
3.10 moles SiO2 (1 mole Si/1 mole SiO2)(6.022 X 1023/1 mole Si) = 1.87 X 1024 atoms of silicon =====================
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.
