The number of moles of helium atoms present in 9.033 × 1024 atoms of helium is

To find the number of moles, you can use Avogadro's number, which is 6.022 x 10^23 atoms/mole.

Step 1: Identify the given values. The given value is the number of atoms, which is 9.033 x 10^24 atoms of helium.

Step 2: Use Avogadro's number to convert atoms to moles. The formula to convert atoms to moles is:

Number of moles = Number of atoms / Avogadro's number

Step 3: Substitute the given values into the formula. Number of moles = 9.033 x 10^24 atoms / 6.022 x 10^23 atoms/mole

Step 4: Calculate the result. The result is approximately 15 moles of helium.
