To determine the ksp value of hg2i2, a chemist obtained a solid sample of hg2i2 in which some of the iodine is present as radioactive 131i. the count rate of the hg2i2 sample is 5.0 x 10^11 counts per minute per mole of i. an excess amount of hg2i2 (s) is placed into some water, and the solid is allowed to come to equilibrium with its respective ions. a 150.0-ml sample of the saturated solution is withdrawn and the radioactivity measured at 33 counts per minute. from this information, calculate the ksp value for hg2i2.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
