Answer: The molality of solution is 0.66 mole/kg
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
= weight of solvent in g
moles of =
Now put all the given values in the formula of molality, we get
Therefore, the molality of solution is 0.66 mole/kg
Answer:- 27.7 grams of are produced.
Solution:- The balanced equation is:
let's convert the grams of each reactant to moles and calculate the grams of the product and see which one gives least amount of the product. This least amount would be the answer as the least amount we get is from the limiting reactant.
Molar mass of = 207.2+2(126.90) = 461 gram per mol
let's do the calculations for the grams of the product for the given grams of each of the reactant:
=
=
From above calculations, NaI gives least amount of , so the answer is, 27.7 g of
are produced.
