a) What is the molecular weight of a sample weighing 0.357g dissolved in 22.5mL cyclohexane (20.4°C/m) if the final solution had a freezing point of 3.66°C? (the normal freezing point of cyclohexane is 6.6°C.)

b) What is the molarity of this solution (you're missing some information, perhaps consult the CRC, wikipedia, your lab manual)?

c) What if your molecule dissociated into 2 different species in solution (“i” = 2), what is the new calculated molecular weight?

A sample of antihistamine, bropheniramine maleate, weighing 4.6330g was dissolved in alcohol and decomposed with metallic sodium. The resulting solution was treated with 10.00mL of 0.2500 M AgNO3, an amount sufficient to precipitate all of the liberated bromide ion as AgBr. The excess AgNO3 was titrated with 0.1214 M KSCN, requiring 14.42mL to reach an end point: Ag+  + SCN-   --> AgSCN(s) , calculate the % Br in the sample. what additional piece of information is needed to determine the percentage...

A steel sample weighing 1.000 g is dissolved in acids and treated with persulfate and periodate to oxidize Mn to MnO4- and Cr to Cr2O7-. The solution is finally diluted to 100.00 mL in a volumetric flask. An aliquot placed in a 1.00-cm cuvette yielded an absorbance of 0.113 at 440 nm and of 1.304 at 545 nm. The absorbance for a reagent blank was 0.005 at 440 nm and 0.008 at 545 nm. Calculate the percentages (m/m) of Cr...

A sample of a chromium-containing alloy weighing 3.450 g was dissolved in acid, and all the chromium in the sample was oxidized to 2CrO42–. It was then found that 3.18 g of Na2SO3 was required to reduce the 2CrO42– to CrO2– in a basic solution, with the SO32– being oxidized to SO42–. Write a balanced equation for the reaction of 2CrO42– with SO32- in a basic solution. How many grams of chromium were in the alloy sample? What was the...
