Answer:
-- Volume of base used
--- Molarity of base
Explanation:
Given
-- Volume of acid used
--- Buret Initial reading
--- Buret Final reading
--- Molarity of the acid
Solving (a): Volume of base used (VB)
This is calculated by subtracting the initial reading from the final reading of the base buret.
i.e.
Solving (b): Molarity base (MB)
This is calculated using:
Make MB the subject
This gives:
Solving (c): <em>There is no such thing as average molarity</em>
Answer : The number of electrons in an atom is, 2 electrons
Explanation :
As we know that there are four quantum numbers which are principle quantum number, azimuthal quantum number, magnetic quantum number and spin magnetic quantum number.
The Principle quantum number, n = 3. That means the electron present in the third energy level.
The Azimuthal quantum number, l = 2. That means the electron present in the d sub-shell.
The magnetic quantum number, . That means it shows the 2 electrons present in one of the five 3d orbitals.
Hence, the number of electrons in an atom is, 2 electrons
