Here's how to calculate the number of moles in 75 grams of sulfur:

1. Find the molar mass of sulfur:

* The molar mass of sulfur (S) is 32.06 g/mol (you can find this on the periodic table).

2. Use the formula:

* moles = mass / molar mass

3. Plug in the values:

* moles = 75 g / 32.06 g/mol

4. Calculate:

* moles ≈ 2.34 mol

Therefore, there are approximately 2.34 moles in 75 grams of sulfur.
