znk

Mass of Ni = 0.015 mol Ni × (58.693 g Ni/1 mol Ni) = 0.88 g Ni

0.13g is the mass of nickel that participated in the chemical reaction.

What are moles?

A mole is defined as 6.02214076 × [tex]10^{23}[/tex] of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

[tex]Moles = \frac{mass}{molar \;mass}[/tex]

[tex]0.015 = \frac{mass}{8.693 g g/mole.}[/tex]

[tex]Mass =12.34 mol x 342.14 g/mole[/tex]

= 0.130395g =0.13g

Hence, 0.13g is the mass of nickel that participated in the chemical reaction.
