Answer:
pH = 2.77
Explanation:
Data Given:
degree of dissociation Ka = 0.057
Concentration of Methanoic acid = 0.005 M
pH = ?
Solution:
First we calculate Hydrogen ion concentration
Formula will be used
[H⁺] = . . . . . . (1)
where
Ka = degree of dissociation
c = concentration
Put values in formula 1
[H⁺] = . . . . . . (1)
[H⁺] = 0.0017 M
Now Calculate the pH
As we know
pH = -log [H⁺] . . . . . .(2)
Put values in equation
pH = - log [ 0.0017 M]
pH = - [-2.77]
pH = 2.77
So,
pH of methanoic acid = 2.77
Nomenclature and common formula. When part of a salt, the formula of the acetate ion is written as CH3CO2−, C2H3O2−, or CH3COO−. Chemists abbreviate acetate as OAc− or, less commonly, AcO−. Thus, HOAc is the abbreviation for acetic acid, NaOAc for sodium acetate, and EtOAc for ethyl acetate.
Answer:
112.18 g.
Explanation:
you're using stoichiometry to find the mass of the compound S₃O.
It releases all types of pollution into the air, as well as potentially endangering birds and other wildlife that live near that forest.
hope that helps!
