A 13.4 mL sample of vinegar, containing acetic acid, HC2H3O2, was titrated using 0.554 M NaOH solution. The titration required 20.65 mL of the base.
Assuming the density of the vinegar to be 1.0 g mL-1, what was the percent (by mass) of acetic acid in the vinegar?
A similar question was asked before, but the formatting of the answer made it unreadable. So, I am asking it again. I have a thermodynamic system with three states in the canonical ensemble
The atomic mass of element X is 29.42 amu. A 33.22 g sample of X combines with 92.10 g of another element, Y to form a compound XY, Calculate the atomic mass of Y.
A renowned laboratory reports a quadruple-point coordinates of 10.2 Mbar and 24.1 degrees C for four-phase equilibrium of allotropic solid forms
Use the Solubility Rules to write the dissociation equation when the ionic compounds are placed in water. If substances do not dissolve, state "no reaction" 1) magnesium chlorate
Washing soda is often added to detergent formulations to make the wash water more basic. What is the formula of the NONHYDRATED form of washing soda? Does it increase or decreased the pH of the wash water?
In conducting a titration of 75.00mL of a certain triprotic acid with 0.0800 M NaOH the following information was recorded. a. the first equivalence point was observed at pH 3.96 after the addition of 12.4 mL of NaOH
Give the products of the following reactions (no reaction mechanism necessary). if the products can exist as stereoisomers, show which stereoisomers are obtained.
Calculate the change in entropy (in J/K) for the following reaction at 298 K: C(s) + H2O(g) ? CO(g) + H2(g) Use entropy for graphite (diamond is too expensive).
Assuming the same calorimeter constant you determined (I got 217.8 J/degreesC) and assuiming NaOH is the limiting reagent, what is delta H(neutralization) in kJ/mol?
Consider a container sealed with a small opening. A mixture of several gases are added to the container. Assuming the gases do not react, indicate the order that the gases escape out of the container
Using the de Broglie and Planck-Einstein formulas, and considering (A) a helium atom with a kinetic energy of 0.0025eV (i.e, thermal energy at 300K) and (B) a baseball (mass=500g) moving at 49m/s, evaluate and interpret the wavelength and frequenc..
how many grams of sodium acetate must be added to 1.00 L of a .200 M acetic acid solution to form a buffer of 4.20? Ka value for acetic acid is 1.8x10^-5.
