Molality of C2H5OH is 1.1.27m.
What is Molality?
Molality is no.of moles present in One Kg solution .
Molality is represented by m
m= no.of moles/ weigt of solution in kg
Given is Molarity= 51.30M
molar mass of C2H5OH is 46g / mol , Density =0.9349g/ ml
Density=m/V
V = 107 ml
Molarity= no of moles/ Volume
51.5×46×107= x × 1000
weight of C2H5OH = 27.7g
molality = 27.7/1000××46
m= 1.27m

Explanation:
coz anything above 7.0 is Base on PH paper !
Hope you got it.
Answer:
Excuse me if i am worng but i think it is B
Explanation:
Answer is: <span>pH of the water is 8.33, this is basic solution (pH is greater than seven).
</span>[H₃O+] = 4.60·10⁻⁹ M; equilibrium concentration of hydronium ion.
pH = -log[H₃<span>O+].
</span>pH = -log(4.60·10⁻⁹ M).
pH = 8.33.
pH (potential of
hydrogen) is a numeric scale used to specify the acidity or basicity <span>an aqueous
solution.
