chemist is trying to prepare a solution of molarity 1.60 M by diluting a 2.13 M solution. This is a dilution equation and dilution formula needs to be used
c1v1 = c2v2
where c1 is concentration and v1 is volume of the more concentrated solution
c2 is concentration and v2 is volume of the diluted solution to be prepared
substituting the values in the equation
2.13 M x 1.24 L = 1.60 M x v2
v2 = 1.65 L
the volume of the diluted solution is 1.65 L

Eleanor wants to show her class a comparison of melting
rates between two different solids when heat is applied. A graph would be more
suitable than a table to show her data because the she can see the trend line
of the effects of melting than the table.
The two parts of a solution are a Solute and the other one is a Solvent. The Solute is the substance that dissolves, and the Solvent is the majority of the solution.
The correct answer is the degree of exactness in a measurement
