Answer:
The correct answer is b. 1280 cm^2
Answer:
273.9 fathom
Explanation:
Fathom (ftm) and rod are the units of length used in the imperial and the U.S. customary systems.
Fathom is an unit used for the measurement of depth of water. It is equal to 1.8288 m.
Rod, also known as perch or pole, is equal to 5.0292 m.
∵ 1 fathom = 0.364 rod
and 1 rod = 2.75 fathom
∴ 99.6 rod = 99.6 × 2.75 fathom = 273.9 fathom
<u>Therefore, maximum depth of Lake Tahoe = 99.6 rod = 273.9 fathom</u>

Answer:
Osmotic pressure is a measure of a solution's tendency to attract or take in water from another solution when the two solutions are separated by a semipermeable membrane
The order of increasing osmotic pressure is
- 0.7% KCl
- 1.5% KCl
- 1.8% KCl
- 5.0% KCl
- 8.6% KCl
Explanation:
Osmotic pressure is the strength of movement of the solvent of a solution through a semipermeable membrane separating solutions of different concentration thereby causing the solvent (such as water) to move from a region of high solute concentration to a region of lower solute concentration.
The amount of osmotic pressure through a semipermeable membrane separating solutions of different concentration is given by
π = i×M×R×T
π = osmotic pressure
i = van't Hoff's factor
(M) = molar concentration
(T) = temperature in kelvin
R = ideal gas constant (0.08206 L atm mol⁻¹K⁻¹)
As seen above , the osmotic pressure is directly proportional to the concentration of the solution thus in the order of increasing osmotic pressure we have
- 0.7% KCl
- 1.5% KCl
- 1.8% KCl
- 5.0% KCl
- 8.6% KCl
