John Wohlwend Nowhere in this question was it indicated that it was a Troy ounce they were asking about. You would have been correct had they so specified, but they did not. The fact is, avoirdupois ounces are divided into grains also. Obviously, a troy ounce is a bit heavier than a regular ounce. One regular ounce is 28.35 grams or 437.5 grains, while a troy ounce is 31.1 grams or 480 grains. You made a false assumption concerning this question and that led you to the wrong answer, so you were credited with a wrong answer. It is entirely fair.

Well, I must bid you all goodbye. I'm sick of the adds. They pop up between and during every question in the quiz. Not to mention the first grade question. Stick me with a fork...I'm done
