Answer to Question #250517 in Organic Chemistry for hos

Question

Suppose that a volume of 5.0 cm³ of acetic anhydride (density = 1.08 g·cm⁻³, molar mass = 102.087 g·mol⁻¹) is hydrolysed completely and the resulting solution is made up to 100.0 cm³ in a volumetric flask. Calculate the volume in cm³ of 0.496 mol·dm⁻³ sodium hydroxide required to titrate a 10.0 cm³ sample of this solution

Answer 1

We have to start with mL, turn them into g, then intomoles.

The molecular formula of acetic anhydride is(CH3CO)2O(molecular mass of 102g).
