Answer :
To find the mass of [tex]\(6.02 \times 10^{23}\)[/tex] atoms of potassium, follow these steps:
1. Understand the meaning of atomic mass: The atomic mass of potassium, given as 39.1, represents the mass of one mole of potassium atoms. The units for atomic mass are typically grams per mole (g/mol).
2. Use Avogadro's number: Avogadro's number, [tex]\(6.02 \times 10^{23}\)[/tex], describes the number of atoms (or molecules) in one mole of a substance.
3. Relate atomic mass to mole: Since 39.1 g is the mass of one mole of potassium, which is exactly [tex]\(6.02 \times 10^{23}\)[/tex] atoms, we can equate this information to find the answer.
4. Conclusion: Therefore, the mass of [tex]\(6.02 \times 10^{23}\)[/tex] (one mole) of potassium atoms is 39.1 grams.
Considering these steps, the correct answer is B. [tex]\(39.1 \, \text{g}\)[/tex].
