The molarity of the diluted solution is 0.2706 M.
Given,
M₁ = 1.1 M
V₁ = 123 mL
V₂ = 500.0 mL
The dilution law formula is M₁V₁ = M₂V₂
1.1*123=M₂*500
M₂=0.2706 M
<h3 /><h3>Molarity </h3>
Molarity, a concentration unit used in chemistry, is determined by dividing the number of moles of a solute by the number of liters of solution. The phrase "molar concentration" (also known as "molarity," "amount concentration," or "substance concentration") refers to the amount of a substance per unit volume of solution and is used to describe the concentration of a chemical species, specifically a solute, in a solution. The most frequent measure of molarity in chemistry is the number of moles per liter, denoted by the unit symbol mol/L or mol/dm3 in SI units. A solution with a concentration of 1 mol/L is referred to as 1 molar, or 1 M.

Mountain chains are formed by the action of different tectonic plates drifting
Answer: No
Explanation:
Firstly, the molar mass of the dissolved solid is not given. This is necessary to calculate the number of moles present in solution. Secondly, solubility always has to do with temperature and the specified temperature is 27°c and not 21°c. This makes it impossible to calculate the solubility at 21°c. Further information must supplied before the solubility at 21°c can be accurately calculated.
For a second order kinetics, the reaction rate expression would be
-r = -dCa / dt = kCa^2 where k is the reaction constant and Ca is the concentration of reactant A.
Integrating this from Cao to Caf, will have the expression,
1/Caf - 1/Cao = kt
Substituting the given values and calculating for k,
1/0.00650 - 1/0.0100 = k(100)
k = 0.538 / M-s
