mass = 12.2 kg
Explanation:
To find the mass we use the following formula (Newton's Second Law of Motion):
force = mass × acceleration
mass = force / acceleration
mass = 2.32 N / 0.19 m/s²
mass = 12.2 kg

The Change in Gibb's free energy, ΔG for the reaction at 298K is; -56.92KJ.
<h3>Gibb's free energy of reactions</h3>
It follows from the Gibb's free energy formula as expressed in terms of Enthalpy and Entropy that;
On this note, it follows that;
Hence, the Gibb's free energy for the reaction is;
- ΔG = 14.6 - 71.52
- ΔG = -56.92KJ
Remarks: The question requires that we determine the Gibb's free energy for the reaction at 298K.

The answer is: Cl2.
Chlorine is diatomic molecule made of two chlorine atoms.
Diatomic molecules are molecules made of two atoms.
They can be homonuclear (molecule made of two atoms of the same element) and heteronuclear (molecule made of two different atoms).
Chlorine (Cl) is halogen element.
Halogen elements are in group 17: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). They are very reactive and easily form many compounds.
We are given that:
100 mL total solution with 1:50 povidone iodine solution
This means that there is 1 mL of povidone iodine solution
per 50 mL of total solution. Since we are given a total of 100 mL solution,
therefore we have an initial amount of:
pure povidone iodine solution = 2 mL
This amount of pure povidone iodine solution is added or
diluted (most perhaps with water) to make a total of 1000 mL total solution,
therefore the new ratio is:
2:1000 povidone iodine solution
By dividing both sides by 2, this simplifies to
1:500 povidone iodine solution
Answer:
1:500
