Please show all of your work and any explanations as I am trying to learn how to do this. I don't JUST want the answers. I need the animals, but really WANT to know how to work these problems. :) Thank you! Give the concentration of the following solution in molality and molarity. A 10 mL aliquot of a 10 M solution diluted to 250 mL A 25 mL aliquot of a 10 M solution diluted to 250 mL A 57 gram beaker that weighs 82 grams after NaCl is added transfers all of the NaCl into a 100 mL volumetric flask and dilutes it to the mark.
In combustion analysis, 2.00mg of vitamin C yielded 3.00mg CO2 and 0.816mg H2o. From mass spectrometry, it was found that the molecular weight of vitamin C is 176amu. Determine the mass composition of vitamin C, its empirical formula, and its molecul..
Calculate the percent yield for an experiment in which 5.50 g of SOCl2 was obtained in a reaction of 5.80 g of SO2 with excess PCl5
In one experiment, the mass of water is 93.0 grams, the initial temperature of the water is 67.2oC, the mass of liquid nitrogen added to the water is 57.8 grams, and the final temperature of the water, after the liquid nitrogen has vaporized, is 3..
When anisole is nitrated with nitric acid/sulfuric acid, what product or product mixture is formed?
Given that Iron(III) oxide or ferric oxide (molar mass = 159.7 g/mol) reacts with Carbon monoxide (molar mass = 28.0 g/mol).
Explain why the boiling point of an aqueous solution that is 1.0 m in glucose (C6H12O6) is 100.51oC whereas The boiling point of an aqueous solution that is 1.0 m in NaCl is 101.02 oC .
Calculate the molar solubility of AgBr in a 1.00 M aqueous solution of ammonia. Then calculate the solubility of AgBr in pure water, and compare the two solubilities. (Ksp for silver bromide is 7.7x10 -13 and Kf for Ag(NH3)2+ is 1.6x10^7)
solution containing a silver electrode. Determine the initial voltage of the cell at 298 K
Since the sample is an unknown solid, I will have to make a solution without knowing exactly what to mix. In your expertise, how much of the solid do you expect to dissolve in what volume of water and what is your reasons for choosing these amount..
