Answer :
To determine the mass of [tex]\(6.02 \times 10^{23}\)[/tex] atoms of potassium, we start by understanding a few key facts:
1. Atomic Mass: The atomic mass of potassium is given as 39.1 atomic mass units (amu), but when referring to a mole of atoms, it is considered to be 39.1 grams per mole.
2. Avogadro's Number: This number [tex]\(6.02 \times 10^{23}\)[/tex] represents Avogadro's constant, which is the number of atoms in one mole of any substance.
Given this information, we can observe the following:
- The atomic mass in grams of one mole (which is [tex]\(6.02 \times 10^{23}\)[/tex] atoms) of any element is equal to its atomic mass listed in grams per mole.
- For potassium, the atomic mass and, therefore, the mass of one mole of potassium atoms is 39.1 grams.
So, when we have [tex]\(6.02 \times 10^{23}\)[/tex] atoms of potassium, this is precisely one mole. Thus, the mass of these atoms is:
- 39.1 grams
Therefore, the correct answer to the question is:
B. 39.1 g
