Answer:
Taking into account the definition of avogadro's number, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.
First, you have to know that it is called Avogadro's Number or Avogadro's Constant. By Avogadro's number it is understood the number of elementary entities (that is, of atoms, electrons, ions, molecules) that exist in a mole of any substance. Its value is 6.023×10²³ particles per mole.
Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression.
Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 6.023×10²³ atoms are contained in 1 mole of silver, then 1.8×10²⁰ atoms are contained in how many moles of silver?
amount of moles of silver= (1.8×10²⁰ atoms × 1 mole)÷ 6.023×10²³ atoms
amount of moles of silver= 2.98×10⁻⁴ moles
Finally, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.
The Fifteenth reconstruction amendment (1869) was intended to protect freedmen against the injustices depicted in this cartoon.
In 1869, Congress passed a constitutional amendment guaranteeing black suffrage.
The Civil War Amendments, often known as the Reconstruction Amendments, are the Thirteenth, Fourteenth, and Fifteenth Amendments to the United States Constitution, which were ratified between 1865 and 1870.
The Thirteenth Amendment (1864) outlawed slavery and involuntary servitude.
The Fourteenth Amendment (1866) emphasizes citizenship rights and equal legal protection for all people.
The Fifteenth Amendment (1869) forbids discrimination in citizens' voting rights based on "race, color, or prior condition of servitude."
