Based on the average number of moles of IO3- in your samples, and the initial volume of those samples, what is the solubility of Ca(IO3)2 in mol/L of the saturated solution in pure water?
A sample of air at 15 psi is compressed at constant temperature from 555ml to 275ml. Calculate the resulting pressure.
assuming that the atomspher is locally isothermal, the air density variation with pressure is giving by B=B0*(P/P0) where B is density ,p is pressure , and the subscript 0 denotes conditions at the earth's surface.
A car gets 9.2 kilometers to a liter of gasoline. Assuming that gasoline is 100% octane which has a specific gravity of .69, how many liters of air (21% oxygen by volume at STP) will be requiered to burn the gasoline for a 1250 km trip? assume com..
