Science

In science today we learned about concentration.  Not concentration like you are thinking really hard, but concentration as in, amount of materials in a mixture.  So here is a problem, 

 80 mL of water and 2 scoops of salt, or 40 mL of water and 3 scoops of salt.  Which one has the most concentration?  Answer: the one with 40 mL of water and 3 scoops of salt, because, the other one is more watered-down because it has more water.  So the less water it has, the more concentration it has.
