Answer:
There are
Explanation:
In this problem, we need to find the number of molecules in
mol of
.
The molar mass of
is 
No of moles = mass/molar mass
We can find mass from above formula.

Also,
No of moles = no of molecules/Avogadro number

Hence, there are
They can use the properties to test and come to some kind of conslusion about the object because in some way it's gotta correlate back to one of the different properties of matter.
