3) My car has an internal volume of 2600 liters. If the sun heats my car from a
temperature of 200 C to a temperature of 550 C, the pressure inside the car is 760 mm Hg.
How many moles of gas are in my car?

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
