WebA 1:5 dilution (also known as a “1 to 5” dilution) involves mixing 1 unit volume of solute (the item to be diluted) with 4 unit volume of solvent medium (therefore, 1 + 4 = 5 = … WebOct 18, 2024 · Solution. It does not matter which set of conditions is labeled 1 or 2, as long as the conditions are paired together properly. Using the dilution equation, we have. (2.19 M) (25.0 mL) = M 2 (72.8 mL) Solving for the second concentration (noting that the milliliter units cancel), M 2 = 0.752 M. The concentration of the solution has decreased.
