Answer :
To determine the molar mass of potassium, we refer to the periodic table of elements, where we can find the atomic masses of elements. The atomic mass of an element is expressed in atomic mass units (amu) and also corresponds to the molar mass of the element in grams per mole.
1. Identifying Potassium in the Periodic Table: Potassium is represented by the symbol "K" on the periodic table.
2. Locating the Atomic Mass: The atomic mass of potassium is approximately 39.1 amu. This value tells us the average mass of one mole of potassium atoms.
3. Understanding Molar Mass: The molar mass is the mass of one mole of a substance, expressed in grams per mole. For elements, the molar mass in grams per mole is numerically equal to the atomic mass in amu.
Therefore, the molar mass of potassium is 39.1 grams per mole. From the options given, the correct answer is 39.1 g.
