Answer:
(a).molar mass=(12×9)+(1×8)+(16×4)
=180.0g
(b).moles of Aspirin
moles=mass(g)÷molar mass
=360.4÷180.0
=2.002moles
(c). molecules of Aspirin
To get molecules just multiply moles of Aspirin by Avocado number.
=2.002×6.022×10^23
=1.206×10^24 molecules
(d) number of carbon atoms
=12×9
=108 carbon
Answer:
Explanation:
Hello there!
In this case, since the buffer is not given, we assume it is based off ammonia, it means the ammonia-ammonium buffer, whereas the ammonia is the weak base and the ammonium ion stands for the conjugate acid. In such a way, when adding HI to the solution, the base of the buffer, NH3, reacts with the former to promote the following chemical reaction:
Because the HI is totally ionized in solution so the iodide ion becomes an spectator one.
Best regards!
Answer:
The order of increasing number of micro states in the resulting system is 3 < 1 < 5 < 2 < 4.
Explanation:
A micro state is a specific way in which we can arrange the energy of the system.Many of then are indistinguishable to each other higher the entropy.
Increase the temperature a volume makes more micro states.
Therefore, the descriptions in order of the increasing number of micro states .
Therefore, the increasing order of micro states in the resulting system is as follows.
3 < 1 < 5 < 2 < 4.
