Answer: Check explanation please.
Explanation:
Before diving into the question,let us consider some important facts and definitions.
WHAT IS OSMOLARITY? Osmolarity is the number of OSMOLES of solute per litre of the solution. The unit of osmolary is OSMOLE. Nowadays, osmolarity has become a term used in the past, now osmolarity is called osmotic concentration.
OSMOLARITY can be calculated using; Σ(osmotic coefficient × number of ion × the solute molar concentration).
BACK TO THE QUESTION; ALBUMIN is a PROTEIN. Protein is a large molecule and it contributes an insignificant amount to osmolarity(around 0.6 Mosmole/litre).
Also, if we have the osmotic coefficient to be between zero and one, there is going to be great DISSOCIATION.
Explanation:
As molarity is the number of moles placed in a liter of solution. Therefore, no. of mole = Molarity × volume of solution in liter
Hence, moles of
will be calculated as follows.
No. of mole of
=
= 0.0168 mole
According to the given reaction, 2 mole of
react with 4 mole of KI.
Therefore, for 0.0168 mole amount of
required will be as follows.
=
= 0.0337 mole of KI
Hence, volume of KI required will be calculated as follows.
Volume = 
Volume of KI =
= 0.1614 liter
= 161.4 ml (as 1 L = 1000 mL)
Thus, we can conclude that 161.4 ml volume of a 0.2089 M KI is required for the given situation.
Answer: As the temperature of the thermometer has increased it shows that that the reaction that has taken place was exothermic. In exothermic reactions heat is given out and temperature of the surroundings increases which is indicated by the increase in temperature of the thermometer.
