Answer:

0.4773 moles Ca

Explanation:

To find the amount of moles, you need to multiply the mass (g) by the atomic mass of calcium. The atomic mass compares the mass of calcium per every one mole. It is important to arrange the ratio in a way that allows for the cancellation of units (grams should be in the denominator). The final answer should have 4 sig figs to match the given value.

Atomic Mass (Ca): 40.078 g/mol

 19.13 g Ca              1 mole
-------------------  x  -------------------  =  0.4773 moles Ca
                              40.078 g
