The Merck Index indicates that 10 mg of guanidine, CH5N3, may be administered for each kg of body weight in the treatment of myasthenia gravis. The nitrogen in a 4-tablet sample that weighed a total of 7.50 g was converted to ammonia by Kjeldahl digestion, followed by distillation into 100.0 mL of 0.1750 M HCl. The analysis was completed by titrating the excess acid with 11.37 mL of 0.1080 M NaOH. How many of these tablets represent a proper dose for patients whose weight is 100 lb (assume that 1 pound, lb, is 0.45 kg).
Calculate the pH of a solution when 0.200 moles of solid NaOH is added to 2.00 liter of 0.250 M HCl. Assume no change in volume.
How many mL of 0.145 M NaOH solution will be required to neutralize 5.00 mL of a 0.829 M HCl solution
Estimate the triple point pressure and temperature of water, given that the standard enthalpies of fusion and vaporization are 6008 j/mol and 43990 J/h at 273.15k and 298.15 k, respectively the vapor pressure of water at 25 c is 23.8 torr
What was the concentration of the original hydroxylamine solution? What is the pH at the equivalence point? Which indicators should be used to detect the endpoint of the titration?
Write balanced net ionic equations for the following reactions in basic solution. Express your answer as a chemical equation. Identify all of the phases in your answer.
nitric acid will give a better yield than acetic acid because with acetic acid some material is converted into benzaldehyde by cleavage of the bond between two oxidized carbon atoms that is activated by both phenyl groups. Any help would be apprec..
A solution is made by mixing equal masses of methanol, CH4O, and ethanol, C2H6O. Determine the mole fraction of each component to at least three significant figures.
If we took EXACTLY 1.00 ml of a 1.000 M solution of Cu(NO3)2 and placed it in 99.000 ml of water and mixed it, then took 2.00 ml of this solution and placed it in 18.000 ml of water.
Iron has a reported average atomic mass of 55.85 amu. If iron has two isotopes, one of which has 29 neutrons and an isotopic abundance of 57.50%, what is the mass of the other isotope?
A sample of oxygen that occupies 1.00x10^6mL at 575 mmHg is subjected to a pressure of 1.25 atm. What will the final volume of the sample be if the temperature is held constant?
Calculate the volume (mL) of a .150 M KOH solution that will completely neutralize 10.0mL of a 0.560 M H3PO4 solution?
Given that the N triple bond energy in N2 gas is 941 KJ/mol and that the O double bond in O2 gas is 494 kJ per mole, calculate the no bond energy in No and ONO
