How many moles of calcium chloride are contained in a 333 gram sample?

Bogdan [553]

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..

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

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

$\frac{333}{110.98}$

Now divide.

$\frac{333}{110.98}=3.00$

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