(2.16x10^24 atoms) x ( 1 mole/ 6.022x10^23 atoms) =
0.3586848223x10^1 which your answer should be 3.59 moles
There are 2.26 x 10^24 silver atoms in 3.75 moles of silver. This is calculated by multiplying Avogadro's number (6.022 x 10^23 atoms/mole) by the number of moles.
To find the number of moles, we can use Avogadro's number. There are 6.022 x 10^23 atoms in 1 mole of any element. Therefore, for 3.4 x 10^24 Pb atoms, the number of moles would be 3.4 x 10^24 atoms / 6.022 x 10^23 atoms/mol.
To calculate the number of atoms in 15.8 moles of boron, you can use Avogadro's number, which is 6.022 x 10^23 atoms/mole. Multiply 15.8 moles by Avogadro's number to get approximately 9.5 x 10^24 atoms of boron.
To find the number of moles of atoms in 1.00 lb of lead, you would first convert the weight to grams (1 lb = 453.592 grams), then divide by the molar mass of lead (207.2 g/mol). This calculation would give you the number of moles of lead atoms in 1 lb of lead, which is approximately 2.19 moles.
3.25 X 10^20 atoms lead (1 mole lead/6.022 X 10^23) = 5.40 X 10^-4 moles lead
(2.16x10^24 atoms) x ( 1 mole/ 6.022x10^23 atoms) = 0.3586848223x10^1 which your answer should be 3.59 moles
2,80 1024 atoms of silicon equals 0,465 moles.
The answer is 15,2 moles.
1,67.1024 argon atoms is equal to 2,773 moles.
56 moles × (6.02 × 1023) = 3.37 × 1024 atoms
To find the number of moles in 2.16 x 10^24 atoms of lead, you would divide the number of atoms by Avogadro's number, which is 6.022 x 10^23 atoms/mol. Thus, 2.16 x 10^24 atoms of lead is equal to 3.59 moles.
