g) A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of m = 0.400 fg (where a femtogram, fg, is 10- -15 and is swimming at a velocity of v = 6.00 μm/s, with an uncertainty in the velocity of 1.00 %. E. coli bacterial cells are around 1 μm (10-6 m) in length. The student is supposed to observe the bacterium and make a drawing. However, the student, having just learned about the Heisenberg uncertainty principle in physics class, complains that she cannot make the drawing. She claims that the uncertainty of the bacterium's position is greater than the microscope's viewing field, and the bacterium is thus impossible to locate. Part A What is the uncertainty of the position of the bacterium?

The simplest of these cells would mimic red blood cells in that they could be filled with oxygen and then injected into a person’s bloodstream. The containers would slowly leak out the oxygen into the blood. Suppose these nanocells are cubic and 25 nm per side. 2. If each nanocell can be pressurized to 85 grams per liter of oxygen, how many grams of oxygen can each cell carry?

= O MATTER Calculating volume by combining the volume of simple shapes A chemistry student in lab needs to fill a temperature-control tank with water. The tank measures 29.0 cm long by 17.0 cm wide by 12.0 cm deep. In addition, as shown in the sketch below, the student needs to allow 2.0 cm between the top of the tank and the top of the water, and a round-bottom flask with a diameter of 9.5 cm will be just barely submerged in the water. Calculate the volume of water in liters which the student needs. Round your answer to the nearest 0.01 L.
