Question

How many moles of f_2 are in 3.7•10^25 molecules of f_2

Answer 1

For
`3.7 * \(10^(25)\)` molecules of
`\(F_2\)`, there are approximately 61.56 moles of
`\(F_2\)` based on Avogadro's number, which relates the number of entities to moles.

To determine the number of moles in a given number of molecules, you can use Avogadro's number, which defines the number of entities (atoms, molecules, etc.) in one mole. Avogadro's number is approximately
`\(6.022 * 10^(23)\)` entities/mol.

In this case, you have
`3.7 * \(10^(25)\)` molecules of
`\(F_2\)`. To find the number of moles, use the formula:

`\[ \text{Number of moles} = \frac{\text{Number of molecules}}{\text{Avogadro's number}}. \]`

Substitute the values:

`\[ \text{Number of moles} = (3.7 * 10^(25))/(6.022 * 10^(23)). \]`

Calculating this yields the number of moles of
`\(F_2\)` molecules.

`\[ \text{Number of moles} \approx 61.56 \text{ moles of } F_2. \]`
