Answer:
1.33 × 10⁻³ m³
Explanation:
Step 1: Given data
Side of the cube (d): 11.0 cm
Step 2: Calculate the volume of the cube (V)
We will use the following expression.
V = d³
V = (11.0 cm)³
V = 1.33 × 10³ cm³
Step 3: Convert "V" to m³
We will use the conversion factor 1 m³ = 10⁶ cm³.
1.33 × 10³ cm³ × (1 m³ / 10⁶ cm³) = 1.33 × 10⁻³ m³
When adjusted for any changes in δh and δs with temperature, the standard free energy change δg∘t at 2400 k is equal to 1.22×105j/mol, then the equilibrium constant at 2400 k is 2.21×10−3. The answer to the statement is 2.21×10−3.
According to the kinetic theory, the mean free path is the average distance a single atom or molecule of an element or compound travels with respect with the other atoms during a collision. The greater the mean free path, the more ideal the behavior of a gas molecule is because intermolecular forces are minimum. To understand which factors affect the mean free path, the equation is written below.
l = μ/P * √(πkT/2m), where
l is the mean free path
μ is the viscosity of the fluid
P is the pressure
k is the Boltzmann's constant
T is the absolute temperature
m is the molar mass
So, here are the general effects of the factors on the mean free path:
Mean free path increases when:
1. The fluid is viscous (↑μ)
2. At low pressures (↓P)
3. At high temperatures (↑T)
4. Very light masses (↓m)
The opposite is also true for when the mean free path decreases. Factors that are not found here have little or no effect.
Take note that one mole of any substance is equal to 6.02 x 10^23 molecules. Thus in converting 5.080 x 10^16 molecules of hydrogen to moles, just divide it with the Avogadro’s number. The answer would be 8.44 x 19^-8 moles...
i think that's it :P :)
