Concentration :
196 g/L and 4 N
<h3> </h3><h3>Further explanation</h3>The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
500 cc of 2M H₂SO₄
V = 500 cc = 0.5 L
mol H₂SO₄
mass H₂SO₄ (MW = 98 g/mol)
concentration in g/L :
concentration in normality
Relationship between normality and molarity
N = M x n (n=valence , amount of H⁺ or OH⁻)
so :
Diatomic molecules are the molecules that you can find them in natural bonded to itself. example: O₂, N₂ or Br₂.
the answer is hydrogen ---> H₂
