Question

An egg shell is made of calcium carbonate (CaCO3). If an egg shell contains 0.0626 moles of CaCO3, how many grams of CaCO3 are in the egg shell?​

Answer 1

6.25 grams of CaCO3 in the egg shell.

Step-by-step explanation:

The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. To find the number of grams of CaCO3 in the egg shell, you can multiply the number of moles (0.0626) by the molar mass (100.09):

0.0626 moles * 100.09 g/mol = 6.25 grams

So, there are 6.25 grams of CaCO3 in the egg shell.
