Assuming that seawater is an aqueous solution of NaCl, what is its molarity? The density of seawater is 1.025 g/mL at 20 °C, and the NaCl concentration is 3.50 mass %.
Propranolol 1C16H21NO22, a so-called beta-blocker that is used for treatment of high blood pressure, is effective at a blood plasma concentration of 50 ng/L. Express this concen- tration of propranolol in the following units: (b) Molarity
Residues of the herbicide atrazine 1C8H14ClN52 in water can be detected at concentrations as low as 0.050 mg>L. Express this concentration of atrazine in the following units: (b) Molarity
How would you prepare each of the following solutions? (b) 100 mL of an aqueous solution whose K+ concentration is 0.075 M
How would you prepare 165 mL of a 0.0268 M solution of benzoic acid 1C7H6O22 in chloroform 1CHCl32?
