Question

what is the molar mass of potassium? 32.066 g/mol 30.974 g/mol 39.098 g/mol 78.196 g/mol

Explanation:

Step1: Recall molar mass of potassium

Potassium (K) has a molar mass that is approximately equal to its atomic weight. From the periodic table, the atomic weight of potassium is about 39.098 g/mol.

Step2: Identify the correct option

Among the given options (32.066 g/mol, 30.974 g/mol, 39.098 g/mol, 78.196 g/mol), 39.098 g/mol matches the molar mass of potassium.

Answer:

39.098 g/mol (the option with 39.098 g/mol, likely the green - colored option in the given choices)
