Hello!
How many moles of nickel (Ni) atoms are in 125 g Ni?
We have the following data:
m (mass) = 125 g
n (number of moles) = ?
MM (Molar mass of Ni) ≈ 58.69 g/mol
Now, let's find the number of moles (n), knowing that:
\(n = \dfrac{m}{MM}\)
\(n = \dfrac{125\:\diagup\!\!\!\!\!g}{58.69\:\diagup\!\!\!\!\!g/mol}\)
\(\boxed{\boxed{n \approx 2.12\:mol}}\end{array}}\qquad\checkmark\)
Answer:
2.12 moles of Nickel (Ni)
