120 barrels = 15120 quarts
To convert from barrels to quarts, you just need to multiply the value in barrels by 126 (the conversion factor).
So, 120 barrels = 120 × 126 = 15120 quarts.
The answer is: Dividing the number of molecules in the sample by Avogadro's number.
The Avogadro’s number is the number of atoms in 12 grams of the isotope carbon-12 (¹²C).
Na is Avogadro number or Avogadro constant (the number of particles, in this example carbon, that are contained in the amount of substance given by one mole).
The Avogadro number has value 6.022·10²³ 1/mol in the International System of Units; Na = 6.022·10²³ 1/mol.
For example:
N(Ba) = 2.62·10²³; number of atoms of barium.
n(Ba) = N(Ba) ÷ Na.
n(Ba) = 1.3·10²⁴ ÷ 6.022·10²³ 1/mol.
n(Ba) = 2.158 mol; amount of substance of barium.
Nitrogenous base. These are Adenine (A), Glycine (G), Thymine (T) or Uracil (U), and Cytosine (C).
A always pairs T (or U in RNA)
G always pairs with C
