The experience of the egg drop project was one that will help you realize that not every way that you try will work, and just because you fail once doesn't mean you can't try again. I believe my egg broke possibly because when I was testing mine I was working with a larger egg. So when it came to the drop it wasn't supported by the walls as much as it should have been. I believe also because the straws on the bottom didn't really reach the egg since it was a smaller egg than what I was practicing

molar concentration of O2 in the Dead Sea. 3. Suppose we make a solution by dissolving 42.5 g of I2 in 1.50 mol of CCl4. a. What is the molality of this solution? b. Suppose we wanted to use our 42.5 g of I2 to make a 0.500 m solution. What volume of CCl4 would we need? The density of CCl4 is 1.589 g/mL. 4. We dissolve 200.0 g of NaCl in 684.5 g of water and find that the density of the solution is 1.15 g/mL. Calculate: a. The % by mass of NaCl

most dilute solution of one of the pesticides. Work your way up to the top concentration of the pesticide, then thoroughly wash the spray top with distilled water. Then you should use the spray top to dispense control solution in order to clean the inside of the spray. Now you can move onto the most dilute solution of the 2nd pesticide and work your way up to the top concentration. When dispensing pesticide solutions it is essential that you use a new clean pipette tip for each solution to avoid

AND MOLAR MASS: AIM The aim of the experiment is to become familiar with the colligative properties and to use them to determine the molar mass of a substance. THEORY A solution consists primarily of solvent and therefore, most of the solution’s properties reflect the solute’s properties. The physical properties that the solution and solute do not share are known as colligative properties and they depend solely on the solute concentration. Some of these properties include vapor pressure lowering
