Bellwork
What is a homogeneous solution?
A homogeneous solution has the same uniform appearance and composition throughout, specifically only one phase present.

Where Are Concentration Units
Where might you find concentration units; I need at least three (3) examples?
![Page 8: Units of Concentration Bio Sciences; Chemicals. Bellwork What is a homogeneous solution? A homogeneous solution has the same uniform appearance and composition](https://reader036.vdocuments.mx/reader036/viewer/2022062517/56649ec55503460f94bcf568/html5/thumbnails/8.jpg)
Common Concentration Units: Percent
Percent (%). The mass/ volume of one components divided by the total mass/ volumew/v: Grams of solute divided by ml of total solution
v/v: Milliliters of solute divided by ml of total solution
w/w: Grams of solute divided by grams of total solution

Compare
What is a similarity and a difference between Molarity and Molality?
![Page 14: Units of Concentration Bio Sciences; Chemicals. Bellwork What is a homogeneous solution? A homogeneous solution has the same uniform appearance and composition](https://reader036.vdocuments.mx/reader036/viewer/2022062517/56649ec55503460f94bcf568/html5/thumbnails/14.jpg)
Normality (N): Is a multiple of molarity either 1, 2, 3, 4, 5, etc.
Or a gram equivalent weight of a solute per liter of solution
Take 1N HCl:1N means 1 molecule of H+ of Cl- per molecule of HCl
Take 2N H2SO4:
2N means 2 molecules of H+ per molecule of H2SO4
Common Concentration Units: Normality
