How is the atomic mass of an element related to a mole?A.The atomic mass, in grams, is the mass of one mole of protons.B.The atomic mass, in grams, is the mass of 6.02 × 1023 moles.C.The atomic mass, in grams, is the mass of one mole of atoms.D.The atomic mass, in grams, is the mass of 6.02 × 1023 electrons.

The correct answer is C. The atomic mass, in grams, is the mass of one mole of atoms.

Here's why:

1. The atomic mass of an element is the weighted average mass of the atoms in a naturally occurring sample of the element. It is usually expressed in atomic mass units (amu), where 1 amu is approximately the mass of a single proton or neutron.

2. A mole is a unit of measurement used in chemistry to express amounts of a chemical substance. It is defined as exactly 6.02214076×10^23 particles, which may be atoms, molecules, ions, or electrons.

3. The atomic mass of an element, expressed in grams, is the mass of one mole of that element. This is because the atomic mass on the periodic table is given in terms of grams/mole. For example, the atomic mass of carbon is approximately 12 amu, so one mole of carbon atoms would have a mass of approximately 12 grams.

4. Therefore, the atomic mass of an element, in grams, is equivalent to the mass of one mole of that element's atoms. This relationship is fundamental to the concept of the mole and allows chemists to easily convert between the mass of a substance and the number of particles it contains.
