Pre Lab 5 - Question 5
5. A group of researchers are interested in a question about the osmolarity of the cells of a particular plant species. The team prepared slabs of tissue of this organism and measured the volumes of these tissue slabs. Then, the slabs were submerged in their own solutions of varying sucrose concentrations. After two hours, the slabs were removed from the sucrose solutions, and the percent difference in volume of the slabs was calculated and...

Atomic emission spectroscopy and the method of standard addition are used to determine the Nat concentration and its uncertainty in an unknown sample. Increasing amounts of a 1.75 μg/m standard Na+ solution are added to a series of volumetric flasks containing 15.00 mL of the unknown 200.0 mL. Atomic emission spectroscopy is then used to measure the emission intensity of each solution. solution. The volumetric flasks are then diluted to a final volume of Unknown volume Standard volume Final volume...
