When comparing 10,000 amu of mercury atoms with 10,000 amu of iron atoms:

Question

Quizplus · Accepted Answer

The number of atoms in a sample is determined by dividing the mass of the sample by the atomic mass unit (amu) of the element. Iron has a lower atomic mass (approximately 56 amu) compared to mercury (approximately 200 amu). Therefore, for the same mass (10,000 amu), there would be more iron atoms than mercury atoms because it takes fewer amu to make up one iron atom than it does to make up one mercury atom.
