Final answer:
The concentration of solutions can be determined by calculating the number of moles of solute and solvent volume, then applying formulas to find molarity or using dilution principles when relevant.
Step-by-step explanation:
To determine the concentration of solutions in which three cells are placed, we must consider several key factors such as the number of moles of solute and the volume of the solvent. In the case where a solution has a molal concentration of 0.63 mol solute per 1.00 kg solvent, we can directly state that there are 0.63 moles of solute present in the solution. If additional information such as the mass of the solute (NaCl) and the density of the solution are given, the molarity can be calculated using these values alongside the given formula.
To calculate the concentration of the solution, we follow the steps that entail determining the number of moles of NaCl present, the volume of water (which may be given in dm³ or liters), and using these to find the molarity of the solution. Furthermore, if the context involves dilution, we can apply the concept that C₁V₁ = C₂V₂, where C represents concentration, V represents volume, and the subscript denotes the initial and final states of dilution, respectively. By using the provided conceptual frames, we can solve for unknown variables to determine the concentration of a given solution.
