Sagot :
Moles of Allura Red = stock volume x stock concentration
= 5.00/1000 x 1.90 x [tex]10^{-4}[/tex] = 9.50 x [tex]10^{-7}[/tex] mol
Volume of diluted solution = 100 mL = 0.100 L
The concentration of diluted solution = moles/volume
= 9.50 x[tex]10^{-7}[/tex]/0.100 = 9.50 x [tex]10^{-6}[/tex] M
Dilution is the process of reducing the concentration of a solute in a solution by simply adding more solvent to the solution, eg water. To dilute a solution, add solvent without adding solute. Dilution is the process of adding solvent to a solution to reduce the concentration of solutes.
Concentration is the process of removing solvent from a solution to increase the concentration of solutes in the solution. Dilution is the process of reducing the concentration of a solute in a solution usually by simply mixing the solute with more solvent. Add water to the solution. Diluting a solution means adding solvent without adding solute.
