Compare the length of a column of mercury to that of a column of water required to produce a pressure of 1.0 bar. the densities of mercury and water at 0C are for mercury 13.596g/cm^3 and for water .99987g/cm^3.
water to give a solution that has a vapor pressure of 37.2 torr at 35 °C? Assume complete dissociation of the solute and ideal solution behavior
If 37.0 mL lead(II) nitrate solution reacts completely with excess sodium iodide solution to yield 0.700 g precipitate, what is the molarity of lead(II) ion in the original solution?
the freezing point of the resulting solution is 3.77*C. The freezing point of pure benzine is 5.48*C. Calculate the molar mass of the compound.
Calculate pCd2 at each of the following points in the titration of 55.00 mL of 0.0020 M Cd2 with 0.0020 M EDTA in the presence of the auxiliary complexing agent NH3.
Iodine-131 is a radioactive isotope. After 7.00 days, 54.7% of a sample of 131I remains.

Estimate the temperature needed to achieve the fusion of deuterium to make an alpha particle. The energy required can be estimated from Coulomb's law
Explain why it is necessary to cinsider water vapor pressure in calculating the atomic mass of an unknown metal. Whould the calculated atomac mass be larger or smaller thatn the true value if water vapor pressure was ignored
the two rarest non-radioactive elements are ruthenium and rhodium, each with an abundance of 1x10^-4 g/t. What is the total mass of each of these elements in the Earth's crust (1 t = 1000kg)?
The smallest unit of charge is -1.6× 10-19 C, which is the charge (in coulombs) of a single electron. Robert Millikan was able to measure the charge on small droplets of oil by suspending them between a pair of electrically charged plates.
