Lesson 16!

Today our amazingly smart and often distracted class put everything we've learned this week together! This includes Molarity, Density, Mass, Molar Mass, Moles, and most of it using Mrs. McDowells chart! Some key things to know is that when a substance is dissolved in water, it adds to the mass of the solution! (Crazy I know). Also, a mole of one substance may have a different molar mass than one mole of another substance, therefore, different solutions of the same concentration can be sorted out by weighing them. Lastly! By comparing contaminants by the number of atoms will greatly give a different end result of the toxicity than comparing by mass! Homework below! Enjoy the three day weekend :)

Btw, I accidentally wrote lesson 15 on the top of the page... But it is lesson 16 homework. Whoops!
