What is the average mass, in grams, of one atom of carbon? A) 5.01 × 10^-22g B) 5.01 × 10²² g C) 1.38 × 10^-25g D) 1.99 × 10^-23g E) 1.99 × 10²³ g

Question

Quizplus · Accepted Answer

The average mass of one atom of carbon is given by the atomic mass of carbon, which is approximately 12 atomic mass units (amu). This can be converted to grams by multiplying by the conversion factor of 1.66 × 10^-24 g/amu. Therefore, the average mass of one atom of carbon is approximately 1.99 × 10^-23 g, which is closest to choice D.
