the number of moles in 1.06*10^23 atoms of tungsten
To find the number of moles in 1.06*10^23 atoms of tungsten, we need to use Avogadro's number which is 6.022*10^23 atoms per mole.
We can use the formula:
Number of moles = Number of atoms / Avogadro's number
Number of moles = 1.06*10^23 / 6.022*10^23
Number of moles = 0.176 moles
Therefore, there are 0.176 moles in 1.06*10^23 atoms of tungsten.
To calculate the number of moles in a given number of atoms, you can use Avogadro's number as a conversion factor. Avogadro's number is approximately 6.022 × 10^23 atoms/mol.
Given:
Number of atoms = 1.06 × 10^23 atoms
To find the number of moles, divide the number of atoms by Avogadro's number:
Number of moles = (Number of atoms) / (Avogadro's number)
Number of moles = (1.06 × 10^23 atoms) / (6.022 × 10^23 atoms/mol)
Now, we can simplify the expression:
Number of moles = (1.06 / 6.022) × (10^23 / 10^23) mol
Number of moles = 0.176 × 1 mol
Therefore, the number of moles in 1.06 × 10^23 atoms of tungsten is approximately 0.176 mol.
