Answer:
1 = 252g, 2 = 2mL, 3 = 1.5mL, 4 = 3g, 5 = 225g, 6 = 0.92g/mL, 7 = 0.75g/mL, 8 = 0.71g/mL, 9 = 1.9mL, 10= 1.11mL, 11 = 76.9g
Explanation:
This problem is testing how well you can move around the equation D = m/v where D = Density (g/mL), m= mass of sample (g), v = volume of sample (mL).
At absolute zero the kinetic energy of the substance will be 0
0.5 = 1/2 = 2/4 = 4/8 = 8/16 = 16/32…
0.75 = 3/4 = 6/8 = 12/16 = 24/32…
Then you can easily find the fractions in between are: 5/8, 9/16, 11/16, 17/32, 19/32, 21/32, 23/32...
Water, Water is not a pure substance. It is a mixture, and Chromatography
Answer:
molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
