When the salt AgI dissolves, it dissociates as follows;
AgI --> Ag⁺ + I⁻
molar solubility of salt is the amount of salt that can be dissolved in 1 L of solution
since the ions dissociated are in 1:1 molar ratio, the molar solubility of the ions are equivalent to the molar solubility of the salt.
ksp is the solubility product constant of the salt
ksp = [Ag⁺][I⁻]
ksp = (9.1 x 10⁻⁹ mol/L)²
ksp = 8.28 x 10⁻¹⁷
Yes because they atom with a stable octet electrons is less reactive it does not need any more electrons while an atom that has an partially filled electrons need more electrons to complete octet structure

First, calculate the change in temperature.
30.5 - 23.2 = 7.3 K
Now we have 3 pieces of data, the units involved are K, J/(g K), and J. We wish to create a result with the units being g. Let's start with the specific heat.
0.90 J/(g K)
Now let's cancel out the K by multiplying by our data with K
0.90 J/(g K) * 7.3 K = 6.57 J/g
Now we want to cancel out the J and get g on top. We can do that by dividing the J value we have by the calculated value above. So
10.3 J / 6.57 J/g = 1.567732116 g
Rounding to 2 significant figures gives us a mass of 1.6 g
Remember, for most problems, simply look at the units you have and what you desire for the units in the final result. By paying attention to this, the math operations you need are pretty automatic.</span>
