Linda used 16.25 mL of 0.4776 M NaOH to neutralize a 10.00 mL sample of orange juice. Assuming all acid in the sample was citric acid, what is the concentration, in M, of citric acid in the orange juice

Explanation:

Citric acid is a tribasic acid , having three ionizable hydrogen in them.

Let the molarity of citric acid  be X .

Normality = 3 X

Using the formula S₁ V₁ = S₂ V₂

.4776 M x 16.25 mL = 10 mL x 3 X

X = .2587

Hence molarity of citric acid is 0.2587 M .

the product of the pressure and volume is also constant

the answer is true. hope it .
