<u>Answer:</u>
(a): The balloon will contain number of molecules now.
(b): The gas law associated with this is Avogadro's law.
<u>Explanation:</u>
Avogadro's law states that the volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature
Mathematically,
(At constant pressure and temperature)
OR
.....(1)
where,
= Initial volume and number of moles
= Final volume and number of moles
We are given:
Putting values in equation 1, we get:
(a):
If number of moles of gas contains X number of molecules
So, number of moles of gas will contain = number of molecules
Hence, the balloon will contain number of molecules now.
(b): The law used is Avogadro's law.

Answer:
The molarity of the acid HX is 6.0 M.
Explanation:
We determine the amount of moles of KOH used to neutralize the acid:
=0.12 moles KOH
Then, we calculate the amount of moles of acid:
0.12 moles KOH×=0.12 moles HX
The molarity of HX is:
=6.0 M
