A cientist makes 300.0 mL of an acetate buffer usin [CH3COOH]o=[NaCH3COO]o=0.075 M. How many mL of 5.0 M NaOH can be added before its buffering capacity is exhausted?
Calculate the mass of oxygen (in mg) dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air. Assume the mole fraction of oxygen in air to be 0.21
When blood is donated, sodium oxalate solution is used to precipitate Ca2+, which triggers clotting. A 108mL sample of blood contains 9.7*10^-5g Ca2+/mL
How do you calculate the force of water hitting a concrete cylindrical pole. The velocity of the water is 2 ft/s, the depth of the water is 10 ft, and diameter of the pole is 3 ft. So what would be the total force exerted on the pole by the water?
Calculate the pH at the equivalence point for the titration of a solution containing 1250.0 mg of hilariamine (MW = 104.75 g/mol, Kb = 7.1×10-4) with 0.1000MHCl solution.
Determine the calculated pH of the solution if initially there is 2.0mL of CH3COOH at an initial concentration of 0.89M and 0.80mL of 1.0M Hydrochloric Acid is combined.
