Question 1043598
.
a chemistry student has 45 milliliters of a 20% salt solution. how many milliliters of salt are in the solution?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Salt is a crystal solid body or a powder media.


And it is not measured in milliliters. It is measured in grams (grams of mass).


And the concentration, in this case, is (gram/gram) dimensionless measure.


So, if the solution is 45 gram in mass, then there is 


{{{45*(20/100)}}} = {{{45*(1/5)}}} = {{{45/5}}} = 9 gram of salt.

==============================


Who gave you this problem ? Your teacher?
Say him/her that the amount of salt is measured in grams, not in milliliters.

If it is you who invented this question, then stop duplicate it.
The question doesn't make sense.
