Calculate the number of moles in 8.50x1015 atoms of 4He.
moles=8.5E15/avagrados number
To calculate the number of moles, we need to use Avogadro's number, which states that 1 mole of any substance contains 6.022 x 10^23 particles (atoms, molecules, ions, etc).
Given that we have 8.50 x 10^15 atoms of 4He, we can use the following conversion factor:
1 mole = 6.022 x 10^23 particles
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 = (8.50 x 10^15 atoms) / (6.022 x 10^23 atoms/mol)
Calculating this value gives us:
Number of moles = 8.50 x 10^15 / 6.022 x 10^23
Number of moles = 1.412 x 10^-8 mole
Therefore, the number of moles in 8.50 x 10^15 atoms of 4He is approximately 1.412 x 10^-8 mole.
To calculate the number of moles in a given number of atoms, you need to use Avogadro's number. Avogadro's number is defined as 6.022 × 10^23 atoms/mole.
The given number of atoms is 8.50x10^15 atoms of 4He.
To calculate the number of moles, we need to divide the given number of atoms by Avogadro's number.
Number of moles = Number of atoms / Avogadro's number
Number of moles = 8.50x10^15 atoms / (6.022 × 10^23 atoms/mole)
Now we can calculate the number of moles:
Number of moles = 8.50x10^15 / (6.022 × 10^23)
Calculating this expression, we get:
Number of moles ≈ 1.411 x 10^-8 moles
Therefore, there are approximately 1.411 x 10^-8 moles in 8.50x10^15 atoms of 4He.
