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:
A silicone atom shares an electron pair with each oxygen atom
Explanation:
Because the silicone dioxide molecule has one silicone atom:two oxygen atoms....
Hence...since silicone has four electrons in the outter shell..which are used for bonding...each oxygen atom shares two electrons(an electron pair) with the silicone atom...so as to fill the outter shell of the oxygen atom
