Question

Quizplus · Accepted Answer

The atomic mass of silicon is 28 u which means that 1 mole of silicon contains 28 grams of silicon. Avogadro's number (6.022 x 10^23) just tells us the number of particles (in this case, silicon atoms) in one mole. So, the mass of 1 mole of silicon is simply 28 g. Choice A is incorrect because 1 mole of silicon is not equal to 1 gram. Choice C is just the numerical value of Avogadro's number, which is not relevant to the question. Choice D is an incorrect value and not related to the question.
