I need help finding how to do the calculations for these
tables. If you could show me how to do the 1st determination/ trial
1 for each of them, I can figure out how to do the second and third
determinations/trials. If you could also show me how to do the
standard deviations, that'd be much appreciated. Thank you!

The enthalpy of solution of KBr in water is about +198 kJ/mol (endothermic). Nevertheless, the solubility of KBr is relatively high. Explain why. A sample consisting of various gases contains 3.5*10^-6 mole fraction of radon. This gas at a total pressure of 36 atm is shaken with water at 30 degree C. Assume that the solubility of radon in water with 1 atm pressure of the gas over...

Problems 1. Oxalic acid dihydrate, HyC204 2H20, is often used as a primary standard for the standardization of base solutions. For a procedure comparable to this experiment, approximately how many grams of oxalic acid dihydrate should be used in order to have a volume of about 15 ml of NaOH solution (approximately 0.15M) for the titration? The acid is diprotic (two H...
