For a tablet containing 500mg vitamin C, Calculate how many mL of 0.095M NaOH are required for titration ( molar mass of ascorbic acid- vitamin c is 1.76.12g/mol)

Question

I am not sure of the conversions to use, how to get started with the question.

Answer 1

Call Ascorbic acid just HA.
HA + NaOH ==> H2O + NaA
mols vitamin C (HA) = grams/molar mass = 0.500/molar mass
mols NaOH required = same since the ratio in the equation is 1:1.
Then M NaOH = mols NaOH/L NaOH. You have M NaOH and mols NaOH, solve for L NaOH and convert to mL.
