# What is the mass of 38.4 mol of the element nickel?

Oct 7, 2016

Approx. $2.2 \cdot k g$.

#### Explanation:

Nickel metal has a molar mass of $58.69 \cdot g \cdot m o {l}^{-} 1.$

And thus the mass of the given quantity $=$

$\text{Number of moles "xx" Molar Mass } =$

$58.69 \cdot g \cdot \cancel{m o {l}^{-} 1} \times 38.4 \cdot \cancel{m o l}$ $=$ ??g

How many nickel atoms are in this quantity?
