Calcium fluoride is added to water until the solution is saturated. The calcium ion concentration in the saturated solution is 2.1 x 10-4 M. Compute the equilibrium constant for the dissolution of calcium fluoride.
Using the same sample of gas ( = 275 , = 43 ), we wish to change the pressure to 2750 with no accompanying change in volume or amount of gas.
The temperature of the mixture is 0? , and the total pressure is 1.00 atm . How many grams of helium are present in the gas mixture? Mass of He =?
