Uremia is caused by kidney failure, leading to the accumulation of urea in the blood. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Molality = (Moles of solute/Mass of solvent in kg) . Moles = 0.5 × 2 = 1 mol . Mass = 1 × 60 = 60 g .

Moles of urea = (8/60) ≈ 0.1333 mol . Molality = (0.1333/0.2) ≈ 0.6665 mol/kg . Δ Tf = 1.86 × 0.6665 ≈ 1.24 K .
Ref: NCERT Class 12 Chemistry > Chapter 1: Solutions > Topic: Colligative Properties - Depression of Freezing Point
Moles of urea = 6/60 = 0.1 mol. Volume = 0.3 L. Molarity = 0.1/0.3 ≈ 0.333 M.

Uremia is a condition in which urea accumulates in the blood due to kidney failure.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Micturition Disorders and Accessory Excretory Organs
Small amounts of urea are excreted through the skin via sweat.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Micturition Disorders and Accessory Excretory Organs
Small amounts of urea are excreted through sweat glands in the skin.

Ureotelism is the process of excreting nitrogenous waste in the form of urea, seen in mammals and amphibians.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Concentration of Urine - Counter Current Mechanism
Ammonia is highly toxic and requires large amounts of water for its elimination, which is why it is excreted by aquatic organisms.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Modes of Excretion - Ammonotelism Ureotelism Uricotelism
Aquatic amphibians are ammonotelic, meaning they excrete ammonia, which requires large amounts of water for elimination.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Modes of Excretion - Ammonotelism Ureotelism Uricotelism
Mammals are ureotelic, excreting urea as their primary nitrogenous waste.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Modes of Excretion - Ammonotelism Ureotelism Uricotelism
Urea is only partially reabsorbed; most of it is excreted in urine.
