a. What is the quantity of aspirin in two tablets, expressed in milligrams?
b. What is the dosage rate of aspirin, expressed in milligrams of aspirin per kilogram of body mass?
c. At the given rate of consumption of aspirin tablets, how many days would it take to consume 1.0 of aspirin?
A zero-order reaction has a constant rate of 1.00×10-4 . If after 80.0 seconds the concentration has dropped to 6.50×10-2 , what was the initial concentration.
Phenol is a common organic compound that may be used as a disinfectant. Its pKa in water is 10.0 while in methanol its pKa = 14.4. Is it a stronger acid in water or methanol? Explain the difference in the pKa for phenol in the different solvents.
Commercial vinegar was tritrated with NaOH solution to determine the content of acetic acid (HC2H3O2). For 20.0 milliliters of vinegar, 32.0 milliliters of 0.500 molar NaOH solution was required. What was the concentration of acetic acid in the vi..
