Answer: They are the same.
Expatiation:
Buoyant force: An upward thrust exerted by any fluid on an object placed in it.
According to Archimedes' principle which states that 'upward thrust exerted by the fluid on an object immersed in a fluid whether partially or fully is equal to the weight of the fluid displaced by the immersed body'.This force acts in the upward direction at the center of mass of the displaced fluid.
Hence, it is correct to say that weight of the water displaced compare to the buoyant force are the same.
Explanation:
(a) Equilibrium constant expression is ratio of concentrations of products over reactants each raised to their power of stoichiometric coefficients.
For example consider an equilibrium which is:
The expression is:
![K_c=\frac {[C]^c[D]^d}{[A]^a[B]^b}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%20%7B%5BC%5D%5Ec%5BD%5D%5Ed%7D%7B%5BA%5D%5Ea%5BB%5D%5Eb%7D)
(b) Equilibrium constant of the chemical reaction is value of the reaction quotient of the reaction at the stage of chemical equilibrium which is a state that is approached by the dynamic chemical system at which the composition of the reactant and the product has no measurable tendency towards the change.
(c) Absorbance is the measure of capacity of the substance to absorb the light of a specific wavelength. Absorbance is equal to the logarithm of reciprocal of transmittance.
(d) The Beer's law relates attenuation of the light to properties of material through which light is travelling.
The expression for the law is:
A = ε × l× c
Where,
A is the absorbance
ε is molar absorptivity coefficient
l is the path length
c is the concentration.
Answer:
Molality, Solvent, Solute, Mole fraction, Molarity.
Explanation:
The expression of concentration that provides the moles of solute per kilograms of solvent is Molality. This in the only expression referred to the solvent.
A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the Solvent is water. When water is present, it is usually considered the solvent.
A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the Solute is sodium chloride. There can be 1 or more solutes in a solution.
If you place 5 moles of sodium chloride and 4 moles of sucrose into 11 moles of water, the Mole fraction of sodium chloride would be 0.25. The mole fraction is equal to the moles of a substance divided by the total number of moles.
A way to express concentration that provides the moles of solute per liter of solution is Molarity.
