-- 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): There is no such thing as average molarity
