Question

How many moles of nickel (Ni) atoms are in 125 g Ni?

Answer 1

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)
