You are asked to analyze a pigment found on a painting by the Italian artist Tintoretto. You discover that the compound is acidic and contains 53.66% C and 42.25% O by mass, with the remainder being hydrogen. You also determine that the compound reacts with NaOH in a 1:1 ratio, and that titration of 0.6401 g of the unknown requires 34.67 mL of 0.0375 M NaOH to reach the endpoint. a. What is the molecular formula of the compound? b. Why do we need to know that the compound reacts with NaOH in a 1:1 ratio
