First calculate for number of moles:
moles Ag = 12 g / (107.87 g / mol)
moles Ag = 0.111 mol
Convert to atoms using Avogadros number:
atoms Ag = 0.111 mol * (6.022 x 10^23 atoms / mol)
atoms Ag = 6.7 x 10^22 atoms
There are 47 electrons per atom, therefore:
Number of electrons = (6.7 x 10^22 atoms) * (47 electrons
/ atom)
<span>Number of electrons = 3.15 x 10^24 electrons</span>
the answer is because when you research that would be the answer
When you understand the etymologies of scientific terms, they make a lot of sense in relation to the term. The etymologies themselves often serve as a reasonably okay definition for the term.
Here's an example, many scientific terms have Greek or Latin etymologies. Take "archaeology" (for an example) Etymologically, it consists of two Greek words "archaeo" (old, ancient) and "logos" (a word, discourse, or study). Therefore, etymologically "archaeology" means "the study of old/ancient things."

The three chemical properties of a penny
Penny ( Pennies: plural; refer to a number of individual coins)
- A chemical property of a substance is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.
<h3>What is chemical property?</h3>
The chemical properties of a substance can be determined by performing experiments that use specific materials or processes with known characteristics.
The following are three chemical properties to consider when choosing an element to make coins:
It should malleable, ductile, and an extremely good conductor of both heat and electricity.
