Step 1: Define

707 g S (Sulfur)

Step 2: Identify Conversions

Molar Mass of S - 32.07 g/mol

Step 3: Convert

Step 4: Round

Our closest answer is d) 22.1 moles of sulfur

This is due to dividing different rounded values.

Explanation:

To convert from moles to grams, we must use the molar mass. This can be found on the Periodic Table.

We are given a sample of sulfur. Look for the symbol S on the table.

This tells us the mass of 1 mole of sulfur. Use this molar mass as a ratio.

Multiply by the given number of grams (707).

Flip the fraction so the grams of sulfur will cancel out.

The number we caluclated is the closest to answer choice D: 22.1 moles of sulfur

the answer is true. hope it .
