C (g) + E (g) <-- --> 2 W (g) Initially, there are 3.5 moles of W placed in a 2.5 L evacuated container. Equilibrium is allowed to establish and the value of K = 2.34 E-5 for the reaction under current conditions. Determine the concentration of E at equilibrium.

A. [E] = 8.352 E -6
B. [E] = 0.00578
C. [E] = 0.00289
D. cannot solve using 5% approximation rule

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
