Problem- Using the appropriate Ksp values, find the concentration of K+ ions in the solution at equilibrium after 500 mL of 0.40 M aqueous Cu(NO3)2 solution has been mixed with 350 mL of 0.20 M aqueous KOH solution. (Enter in M.) (Ksp for Cu(OH)2 is 2.6x10-19).
Now find the concentration of OH? ions in this solution at equilibrium. (Enter in M.)
I need help for above question.
A sample of methane gas at a pressure of 0.801 atm and a temperature of 26.9oC, occupies a volume of 687 mL. If the gas is allowed to expand at constant temperature until its pressure is 0.438 atm, the volume of the gas sample will be
