A saturated solution is defined as a. a concentrated solution.
b. a solution that is in equilibrium with pure solvent.
c. a solution that is in equilibrium with undissolved solute.
d. a solution that is in equilibrium with both pure solvent andundissolved solute. According to the kinetic molecular theory, the pressure of agas in a container will decrease if the number of collisions with the container wallincreases number of moles of the gas increases temperature of the gas decreases volume of the container decreases

volume of the container decreases

Explanation / Answer

us the equation PV=nRT P is pressure in kpa V is volume in liters n is the amount of moles (this is what you are trying to find) R is a constant 8.31 T is temp in Kelvin so 408K for you Once you isolate for n times the n value you got by 6.02 e23 tofind the amount of molecules
