Answer : The mass of nickel have, 15435.47 mg.

Solution : Given,

Moles of nickel = 2.63 moles

Molar mass of nickel = 58.69 g/mole

Formula used :

[tex]\text{Mass of Ni}=\text{Moles of Ni}\times \text{Molar mass of Ni}[/tex]

[tex]\text{Mass of Ni}=(2.63mole)\times (58.69g/mole)=154.3547g=15435.47mg[/tex]

(1 g = 1000 mg)

Therefore, the mass of nickel have, 15435.47 mg.
