3. If you start with 8x1025 molecules of Cl, and 25 grams of KI, how many grams of KCl would be made? Calculate the percent yield if 10.0g of KCl is actually produced.

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.
