An energy level of a certain atom is further divided into the orbitals. There are four (4) orbitals. These are the s orbitals, p orbitals, d orbitals, and f orbitals. They are already arranged above as to how they are to be filled. The number of electrons that each can hold are as follows:
s orbitals = 2 electrons
p orbitals = 6 electrons
d orbitals = 10 electrons
f orbitals = 14 electrons
Hello!:
Molar mass:
HBr = 80.91 g/mol
HNO3 = 63.01 g/mol
Number of moles:
moles HBr = 1.0 / 80.91 => 0.01235 moles of HBr
moles HNO3 = 1.0 / 63.01 => 0.01587 moles of HNO3
So , total moles of H⁺ :
0.01235 + 0.01587 => 0.02822 moles of H⁺
Molarity of solution:
M = n / V
M = 0.02822 / 5.0
M = 0.005644
Therefore:
pH = - log [ H⁺ ]
pH = - log [ 0.005644 ]
pH = 2.25
Hope that helps!
