Answer :
Sure! Let's go through the options to find out the molar mass of potassium.
1. Consider the options:
- 19 g
- 31.0 g
- [tex]\(6.02 \times 10^{23}\)[/tex] grams
- 39.1 g
- 15 g
2. Identifying the correct molar mass:
- Potassium is a chemical element represented by the symbol K and has an atomic number of 19 in the periodic table. The molar mass of potassium is known to be approximately 39.1 grams per mole.
3. Analyzing the options:
- 19 g: This is the atomic number, not the molar mass.
- 31.0 g: This is incorrect; it doesn't correspond to the molar mass of potassium.
- [tex]\(6.02 \times 10^{23}\)[/tex] grams: This represents Avogadro's number, which is the number of atoms or molecules in one mole of a substance, not a mass.
- 39.1 g: This is the correct molar mass of potassium.
- 15 g: This is incorrect and does not match the known molar mass.
4. Selecting the correct answer:
- Based on the evaluation, the correct molar mass of potassium is 39.1 grams.
So, the molar mass of potassium is 39.1 g.
