The average fuel economy for a gasoline powered car is about 45 miles per gallon. The average car in the U. S. is driven about 17000 per year. Calculate the number of gallons of gasoline that are combusted by the average car in the U. S. each year.

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

you need to stop taking that class
