Acetone has a molar mass of 58.1 g/mol and a density of 0.787 g/cm^3. Chloroform has a molar mass of 119.4 g/mol and a density of 1.499 g/cm^3. Estimate the volume of the above mixture using this information.
calculate deltaH in kilojoules for the reaction, assuming that the heat capacity of the calorimeter is 776 j/celsius, that the specific heat of the final solution is the same as that of water(4.184J/G*C), and that the density of the solution is 1...
Serum taken from a patient being treated with lithium for manic-depressive illness was analyzed for lithium concentration. A reading of 251 units was obtained for the intensity of the 671 nm red emission line.
