Question

If a solution is diluted, say by adding 100ml of solvent, does the number of moles of solute change? Does the concentration increase, decrease, or stay the same?

i think it depends on what the solvent is, for example if its water then the concentration would decrease?? please help!!!

Answer 1

adding more solvent, with the same amount of solute, DILUTES the solution. What difference can what the solvent is make?

Answer 2

OH yes, if it is more dilute, the concentration of the solute is LESS.
