Question

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

Answer 1

93 moles

Step-by-step 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 =
`(5.60*10^(25))/(6.022*10^(23))`

n= 93 moles
