Question

Citric acid (H3C6H5O7) is triprotic acid which reacts with NaOH according to the balanced chemical equation shown below what volume of 0.200m Naoh is required to titrate 7.50ml of lemon juice which is 0.245 m in citric acid?
H3C6H5O7+3NaOH->Na3C6H5aO7+ 3H2O
Citric acid is H3C. I assume you meant 0.245 M and not 0.245 m.
mols H3C = M x L = ?
Convert mols H3C to mols NaOH.
Then M NaOH = mols NaOH/L NaOH. You know mols and M, solve for L
