Answer:
Enthalpy of solution is 583.67 J
Explanation:
The mass of water is 143 g
The mass of NaCl added = 12g
Total mass of solution will be = 
The specific heat of solution = specific heat of water = 4.184 J /g °C
The initial temperature = 22.5°C
Final temperature =21.6°
The change in temperature = 
The enthalpy of solution will be equal to the heat change in the solution.
The heat change of solution will be calculated as:


Thus the enthalpy of solution is 583.67 J (Endothermic reaction)
For the purposes of the present discussion, three major categories of sedimentary rocks are recognized: (1) terrigenous clastic sedimentary rocks, (2) carbonates (limestone and dolomite), and (3) noncarbonate chemical sedimentary rocks.
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.
