James is preparing three solutions of salt water. Each of the solutions has the same amount of water in the beaker and a different amounts of salt. In the first beaker, there is one scoop of salt in the beaker. The second beaker has two scoops of salt. The third beaker has three scoops of salt. Which of the beakers is the most dilute solution?
A)
beaker 1
B)
beaker 2
C)
beaker 3
D)
all the beakers are equal in concentration

praxer · Answer

dilution factor of a solution depends on the concentration.

concentration= no. of moles/ unit volume.

no. of moles= mass of the substance given/Molar mass

which means concentration=mass of the substance /unit volume* Molar mass

which means more the given mass of the substance  proportional to  the concentration and less dilution.

so with every increase in the lump of salt the given mass of substance increase which means the concentration increase.

Hence, the Beaker 1 is highly diluted solution.

beaker 1 is highly diluted because the concentration of solute is less in beaker than other two beakers. other two beakers can be called as concentrated solution because amount of solute is much more than solvent as compared to beaker 1
