Answer:
7.055 atm
Explanation:
T = (273 + 37)K = <em>310K</em>
The ideal gas constant =<em> 0.0821</em>atm.L/mol.K
Concentration = (0.90g)*(1mol/58.4g/0.100mL) = 0.154mol/L
Molar mass= Concentration*i
Osmotic pressure = Molar mass *the ideal gas constant*T
OP = (0.154)*(1.8)*(0.0821)*(310) = 7.055 atm

Answer:
Helium and Ethlyene Oxide. Your answer is MASS.
Explanation:
Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. effusion refers to the movement of gas particles through a small hole. Graham's law state's that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.
Explanation:
The partial pressure of an individual gas is equal to the total pressure of the mixture multiplied by the mole fraction of the gas.
Total pressure = 2atm
Mole Fraction = number of moles / total number of moles
Neon
Mole Fraction = 4.46 / 7.35 = 0.607
Partial Pressure = 0.607 * 2 = 1.214 atm
Argon
Mole Fraction = 0.74 / 7.35 = 0.101
Partial Pressure = 0.101 * 2 = 0.202 atm
Xenon
Mole Fraction = 2.15 / 7.35 = 0.293
Partial Pressure = 0.293 * 2 = 0.586 atm
Answer:
Earth is not flat because the spheroidical shape provides a more effective shape in terms of exposed surface area for absorbing and radiating radiation, and also for a relatively more uniform gravity pull on different points on its surface which might not be so for a flat surface.
You live in your country, not mine because you have evolved over time to be more adapted to living in your own kind of envoirment. Members of a certain species (like you and me as humans) have been spread to maximize the survivability of their species compared to if they were clustered to a particular place.
