Problems

This type of dilutions describes the ratio of the solute to the final volume of the diluted solution.

For example, to make a 1:10 dilution of a 1M NaCl solution, you would mix one "part" of the 1M solution with nine "parts" of solvent (probably water), for a total of ten "parts." Therefore, 1:10 dilution means 1 part + 9 parts of water (or other diluent).

Drops

For example: if you needed 10 mL of the 1:10 dilution, then you would mix 1mL of the 1M NaCl with 9mL of water.
Or: if you needed 100mL of the 1:10 dilution, then you would mix 10mL of the 1M NaCl with 90mL of water.
The final concentration of NaCl in both cases is 0.1M.
