Answer & Explanation:

The molar mass of calcium chloride is 110.98 g/mol. We can use this information to solve this problem. We can set up our equation like this..

[tex]\frac{333 g(CaCl2)}{} *\frac{1mol(CaCl2)}{110.98g(CaCl2)}[/tex]

Multiply straight across on the top and straight across on the bottom.

[tex]\frac{333}{110.98}[/tex]

Now divide.

[tex]\frac{333}{110.98}=3.00[/tex]

So, there are 3.00 moles of calcium chloride contained in a 33 gram sample which is answer choice D.
