The term "one gram atom" is used to refer to the amount of an element that is equal to its molar mass in grams.
The molar mass of an element is the mass of one mole of that element. A mole is a unit used in chemistry to express the amount of a substance, and it is defined as the amount of a substance that contains Avogadro's number of particles (approximately 6.022 × 10^23 particles). The molar mass of an element is numerically equal to its atomic mass in atomic mass units (amu).
In the case of silver (Ag), its atomic mass is approximately 107.87 amu. Therefore, one gram atom of silver refers to the amount of silver that has a mass of 107.87 grams.
So, to summarize, one gram atom of silver is equivalent to 107.87 grams of silver, which corresponds to its molar mass.
