Antimony (sb) has two stable isotopes with isotopic masses of 120. 9038 u and 122. 9042 u. What is the natural abundance of the heavier isotope?.
Answers
Answer:
average Atomic mass of thallium = 204.38
let heavier isotope is x%
204.3833 (100) = x(204.9744) + (100-x) 202.9723
20438.33 = 2.0021x + 20297.23
x= 70.476

What mass of glucose (C6H12O6) should be dissolved in 10. 0 kg of water to obtain a solution with a freezing point of -4. 2 ∘C?.
Answers
Answer:
4.1kg
Explanation:
I dont kwon but it was ok in the test
The mass of glucose dissolved in the solution is obtained as 4.734 Kg.
We know that;
ΔT = K m i
ΔT = Freezing point depression
K = freezing constant = 1.86 °C/m
m = molality of solution
i = Van't Hoff factor = 1 (molecular solution)
To find the freezing point depression;
Freezing point depression = Freezing point of pure solvent - Freezing point of solution
Since freezing point of water = 0°C
Freezing point depression = 0°C - (-4. 2 ∘C) = 4. 2 ∘C
The molality of the solution is obtained as follows;
m = ΔT/K i
m = 4. 2 ∘C/ 1.86 °C/m × 1
m = 2.63 m
Molality = number of moles/mass of solvent in Kg
Number of moles = mass/molar mass =
Molar mass of glucose = 180 g/mol
Let the mass of solute be m
2.63 = m/180/10
2.63 = m/1800
m = 2.63 × 1800
m = 4734 g or 4.734 Kg
