How many moles are in 5.60 x 1025 molecules of Calcium carbonate?

93 moles

Explanation:

1 mole of CaCO_3 will have 6.022×10^(23) molecules of CaCO_3 .

Given number of molecules of Calcium carbonate =  5.60 x 10^(25)

Therefore, number of moles n =

n= 93 moles

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
