Which equivalence factor set should you use to convert 126 g c to atoms c? (1 mol c/126 g c)(6.02 x 1023 atoms c/1 mol c.(1 mol c/12.01 g c)(6.02 x 1023 atoms c/1 mol c.(12.01 g c/1 mol c)(1 mol c/6.02 x 1023 atoms c.(12.01 g c/1 mol c)(6.02 x 1023 atoms c/1 mol c)?

The equivalence factor set that should be used is

Explanation:

Molar mass of a substance is defined as the mass of one mole of a substance.

We know that:

Molar mass of carbon atom = 12.01 g/mol

Given mass of carbon atom = 126 grams

Applying unitary method:

12.01 grams of carbon occupies 1 mole

So, 126 grams of carbon will occupy =

According to mole concept:

1 mole of an element contains number of atoms

So, of carbon will contain = number of atoms

Hence, the equivalence factor set that should be used is

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
