Create different molarity solutions
WebMolarity is a way of quantifying the concentration of a solution. Dilution is a way of decreasing the concentration of a solution. Both molarity and dilution are essential … WebBoth "high solvent concentration; low solvent concentration" AND "low solute concentration; high solute concentration" are correct answers. A beaker contains two solutions of salt dissolved in water. The two solutions have different concentrations (measured by molarity, M) and are separated by a membrane that is permeable to salt. diffusion.
