Explanation:
Hypatia is popular for her work in mathematics. She also did some work in the area of astronomy. Her well know work in mathematics is her ideas about conic sections.
She was born the Theon of Alexandria and she was a professional mathematician in her life time.
She was the greatest mathematician of her time and she was telling leader of the Neoplatonist school of philosophy in Alexandria. By so doing, she conquered the culture of sexism in her time.
She was trained by her father in mathematics and eventually replaced him. She was the last major mathematician in the Alexandrian tradition.
Benzene at the same prssure ie the horizontal dotted line, benzene requires the minimal temperature hence its most volatile

Answer:
The answer to your question is below
Explanation:
Depression in freezing point is a colligative property i.e. it depends upon under of solute particles present in solution.
Depression in freezing point (ΔTf) is mathematically expressed as,
ΔTf = Kf X m ............... (1)
where Kf = cryoscopic constant
m = molality of solution
If solvent used is water, Kf = 1.853 K Kg/mol and Freezing point of pure solvent = 0 oC
∴ΔTf = 0.58 K ............... (2)
Substituting 2 in 1 we get
0.58 = 1.853 X m
∴ m = 0.313 m
Thus, molality of solution is 0.313 m
