0.134 moles
Explanation:
In order to solve this, we need to find the molar mass of Chromium, which we can see from the periodic table: it is 51.996 g/mol.
Now, we need to set up an equation to convert grams to moles:
![6.97 grams*\frac{1mol}{51.996grams} =0.134mol](/tpl/images/0660/3768/2a677.png)
Thus, the answer is 0.134 moles of Chromium.
