Microliter conversion

Question

How many microliters of solvent is needed for 0.1g, 0.05g, and 0.009g to have the same content of NaNO3? Also will 0.1g have more liquid solvent because it is the highest concentration?

Answer 1

Answered in a previous post. The 0.1 g will have more solvent, but not because it is the highest concentration, but because it has the greatest mass. Please understand the difference between "content", and "concentration". The content will always be 0.1 g, 0.05 g and 0.009 g. The concentration can vary or be the same. It will vary if you add the same volume of solvent to all. It can be the same if you add proportional amounts of solvent to the different masses. 0.1 g gets 2x the solvent as 0.05 g, and it gets 11.1 x the solvent as the 0.009 g sample. Please see my previous answer for more detailed calculations.
