GK's CHEM BLOG: Unit Cell Volume
http://tchrgk.blogspot.com/2008/03/unit-cell-volume.html
This is an archive of Chemistry and Physical Science student questions and my answers from the FREE tutoring forum: http:/ www.pathwhelp.org. And the now defunct AAC Bulletin Boards at AOL. The smallest repeating unit of s crystal of table salt(the unit cell) is a cube with an edge of .0563nm. If the density of NaCl is 2.17 g/cm 3, what is the mass in grams of one unit cell? The edge of a unit cell in meters is:. 1 nm = 1.00x10 -9m. Since 1 m = 100 cm = 10 2 cm,. 100x10 -9m)(10 2cm/m) = 1.000x10 -7 cm.

Hexane, C6H14, Isomers. Suppose you have 2 L of orange drink containing 50% orange juice and 50% water (by volume). The drink was made from 1 L of orange juice and 1 L of water. You want to dilute this drink so that it contains only 20% orange juice. How much water should you add? N = natural log. M/Mo) = 0.809.
