Answer :
To determine the molar mass of potassium, it is helpful to consult the periodic table of elements. The periodic table provides information on the atomic mass of each element, which corresponds to the molar mass when expressed in grams per mole (g/mol).
For potassium (symbol K), the atomic number is 19, meaning it has 19 protons. The molar mass, located typically beneath the symbol on the periodic table, represents the mass of one mole of potassium atoms.
1. Locate Potassium on the Periodic Table:
- Potassium is found in Group 1, which consists of alkali metals.
2. Read the Molar Mass Information:
- Next to the symbol 'K' on the periodic table, the molar mass is usually indicated.
3. Identify the Molar Mass of Potassium:
- From the periodic table, potassium has a molar mass of approximately 39.1 g/mol.
Therefore, the molar mass of potassium is 39.1 grams per mole, matching the provided result of 39.1 grams.
