Explanation:
1) If we have 1/2 OWLs of Snicker bars, then number of items or Snicker bars :
1 OWL = 7 items (given)
We have 3.5 Snickers bars.
2) If we have 100 OWLs of pencils, then number of items or pencils :
1 OWL = 7 items (given)
We have 700 pencils.
3) If we have 2 OWLs of iron atom, then number of iron atoms :
1 OWL = 7 items (given)
of iron
We have 14 atoms of iron.
Answer:
100.223°C is the boiling point of an aqueous solution.
Explanation:
Osmotic pressure of the solution = π = 10.50 atm
Temperature of the solution =T= 25 °C = 298 .15 K
Concentration of the solution = c
van'y Hoff factor = i = 1 (non electrolyte)
c = 0.429 mol/L = 0.429 mol/kg = m
(density of solution is the same as pure water)
m = molality of the solution
Elevation in boiling point =
T = Boiling point of the pure solvent
= boiling point of the solution
= Molal elevation constant
We have :
(given)
m = 0.429 mol/kg
T = 100° C (water)
100.223°C is the boiling point of an aqueous solution.
