The correct answer is Aurora Borealis
A Van Allen Radiation Belt is a torus of energetic charged particles around the Earth, held in a place by Earth's magnetic field. The Van Allen belts are closely related to the popular aurora where particles strike the upper atmosphere and fluoresce.
Answer:
4.4 × 10⁴ g/mol
Explanation:
The osmotic pressure (π) is a colligative property that can be calculated using the following expression.
π = M × R × T
where,
M: molarity
R: ideal gas constant
T: absolute temperature (27°C + 273.15 = 300 K)
Let's use it to find the molarity of the protein.
M = π / R × T
M = 0.053 atm / (0.082 atm.L/mol.K) × 300 K
M = 2.2 × 10⁻³ M
The molarity of the protein is:
M = mass of the protein / molar mass of the protein × liters of solution
molar mass of the protein = mass of the protein / M × liters of solution
molar mass of the protein = 22 g / 2.2 × 10⁻³ mol/L × 0.226 L
molar mass of the protein = 4.4 × 10⁴ g/mol
From boyles law.
P1v1=P2v2
So,12.3×40=v×60
V= 12.3×40/60
