For a tablet containing 500. mg of vitamin c, calculate how many ml of 0.095 m naoh is required to reach the equivalence point.

mL of NaOH required =29.9mL

Explanation:

Let us calculate the moles of vitamin C in the tablet:

The molar mass of Vitamin C is 176.14 g/mole

Thus we need same number of moles of NaOH to reach the equivalence point.

For NaOH solution:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
