An unknown sample of water is heated from 35.0 0C to 95.0 0C. It absorbs 64,100 Joules of heat. How many grams of water were in the sample?

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
