A student placed 16.0 g of glucose C6H212O6 in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100. mL mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 40.0 mL sample of this glucose solution was diluted to 0.500 \rm L. How many grams of glucose are in 100. mL of the final solution?
After 200 seconds has passed, what is the concentration of sulfates in the drinking water sample.
A sample of 0.2140 g of an unknown monoprotic acid was dissolved in 35.0 mL of water and titrated with 0.0950 M NaOH. The acid required 27.4 mL of base to reach the equivalence point.
What salt is produced in each of the following neutralization reactions?
A zero-order reaction has a constant rate of 1.60×10-4 . If after 35.0 seconds the concentration has dropped to 2.50×10-2 , what was the initial concentration?
Suppose you were given a pure stereoisomer that rotated the plane polarized light either +60 degrees or -120 degrees, i.e a uniform colour is observed for both of these readings.
