calculate the molarity (M) of the solution when water is added to prepare each of the following: a)25.0 mL of a 18.0 M HCl solution is diuted to 500 mL. b)50.0 mL of a 1.50 M NaCl solution is diluted to 125 mL. c)4.50 mL of a 8.50 M KOH solution is diluted to 75.0 mL
compressed reversibly and adiabatically until the temperature reaches 250K. Given that its molar constant-volume heat capacity is 27.5J/Kmol, calculate final pressure and final volume.
The mass spectrum of an organic compound shows the relative abundances of M to be 83.79% and M 1 to be 13.59%. Assuming the peaks are caused by 12C and 13C isotopes,
The population mean of the bulb lifetime is 950 h and the population standard deviation is 50 h. calculate the fraction of bulbs expected to have a lifetime less
derive the rate equation in terms of [NO] and [O2] as well as k ( Assume N2O2 to be in a steady state )
The pressure of the gas remaining in the vessel of unknown volume was 0.882 atm. All the measurements were done at the same temperature. What is the volume of the vessel?
What is the high-T approximation for rotations and vibrations? For which of these two degrees of freedom do you expect this approximation to be genrally valid at room temperature?
Trees in cold climates may be subjected to temperatures as low as -60 C. Estimate the concentration of an aqueous solution in the body of the tree that would remain
fluoride ions, calcium ions, and several other dissolved ions. The ions are evenly distributed throughout the water. Which term or terms could be used to describe this sample of tap water?
It required 29.22 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
A calibration is performed with a standard solution of iron in water. Aniron solution in methyl ethyl ketone is analysed based on this calibrationfunction. Is it likely to yield an accurate result? or would the result be toohigh or too low? Explai..
Why should you store the crucible plus sample in a desiccator after heating and before weighing? why should you heat the sample to constant mass?
