The molar mass of potassium is ________. A)19.00 g/mole B)31.00 g/mole C)6.02 × 10²³ g/mole D)39.10 g/mole E)15.02 g/mole

Question

Quizplus · Accepted Answer

The molar mass of potassium is 39.10 g/mole. This is because the atomic weight of potassium is 39.10 g/mol, and since the molar mass is the same as the atomic weight in grams, the answer is D. A is incorrect because 19.00 g/mole is the atomic weight of fluorine, not potassium. B and E are both incorrect because neither of those numbers is the atomic weight of any element. C is incorrect because it is not a valid answer.
