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 .

b. examine and describe cells

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
