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..


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

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


(333)/(110.98)

Now divide.


(333)/(110.98)=3.00

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