Divide the given number by Avogadro's Number: (3.01 X 1023)/(6.022 X 1023) equals 0.500 moles, to the justified number of significant digits.
Multiply by avagadro's number (6.022x1023) giving 3.203704x1023 atoms
4.65Mol
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 ======================
2.80x10^24 atoms x 1 mole/6.022x10^23 atoms = .465x10^1 mole = 4.65
The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / molTo convert atoms to moles:moles P= 3.78E+24 atoms P1 mol P = 6.28 mol P6.02 x 1023 atoms PMultiply by moles per atom. Atoms cancel out.
2,80 1024 atoms of silicon equals 0,465 moles.
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
2,50 moles of silicon contain 15,055352142.10e23 atoms.
Multiply by avagadro's number (6.022x1023) giving 3.203704x1023 atoms
2.80x10^24 atoms x 1 mol/6.02x10^23 atoms = 4.65 moles
Convert 1.35 × 1024 atoms of carbon to moles of carbon
The answer is 0,465 moles.
How many moles are there in 9.0333x1024 atoms of helium
3.10 moles SiO2 (1 mole Si/1 mole SiO2)(6.022 X 1023/1 mole Si) = 1.87 X 1024 atoms of silicon =====================
1 mole of an element contains 6.022 X 1023 atomsso in 1.4324 moles no. of atoms is 8.659 X 1023 atoms
