Answer:

Did you ask this before, here?

Explanation:

You started with a #10.0*mL# volume of #0.50*mol*L^-1# #NaCl#. The starting moles of solute is...................

#0.50*mol*L^-1xx10.0xx10^-3*L=5.00xx10^-3*mol#

If this is diluted, then CLEARLY the concentration of the sodium chloride decreases, but the amount of moles of #NaCl#, #5.00*mmol# is constant.

Typically we define concentration as..........

#"Molarity"="Moles of solute"/"Litres of solution"#
