What is the percent of li in li3n ?

Li percentage in is 59.8%.

Explanation: The question asks to calculate the mass percentage of Li in .

The formula used for mass percentage of an element in a compound is:

mass percentage =

Atomic mass of Li is 6.94 and atomic mass of N is 14.0.

There are three Li in the given compound. So, the mass of Li in the compound is = 3(6.94) = 20.82

Mass of compound = 20.82 + 14.0 = 34.82

Mass percentage of Li =  = 59.8%

Hence, the percentage of Li in is 59.8%.

the answer is minerals.

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
