In 150 g of water, 1.12 L ( n. a. ) of hydrogen sulfide was dissolved . Determine the mass fraction of hydrogen sulfide in the resulting solution. Give your answer in% with an accuracy of hundredths. For example: 6.78

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

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

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
