A=11.535 2. Determine the density of the garnet endmember pyrope (Mg3Al2Si3O12) using the unit cell dimensions given above. (a) Determine the unit cell volume in Å3. (b) Each unit cell of pyrope contains 8 formula units of Mg3Al2Si3O12. Remembering that 1 mole contains Avogadro's number of formula units, how many unit cells make up one mole of pyrope? (c) Calculate the volume, in Å3, of 1 mole of pyrope. (d) Convert the answer from Å3 to cm3. Be careful with...

One of your intestinal cells compared to one of your skin cells look very different from one another and serve different functions in your body. How are these two cells so different if they all originated from the same cell? O The two cells use a different genetic code. O The two cells have different genes. The two cells lost different genes through developmental differentiation. O The two cells express different genes.

Some cell membranes in the human body have a layer of negative charge on the inside surface and a layer of positive charge of equal magnitude on the outside surface. Suppose that the charge density on either surface is ± 0.50×10−3 C/m2, the cell membrane is 5.00 nm thick, and the cell membrane is made up of tissue with a dielectric constant of 5.40. A) Find the magnitude of E in the membrane between the two layers of charge. E=?...

Cell Membranes and Dielectrics Many cells in the body have a cell membrane whose inner and outer surfaces carry opposite charges, just like the plates of a parallel-plate capacitor. Suppose a typical cell membrane has a thickness of 8.2×10−9 m , and its inner and outer surfaces carry charge densities of -5.3×10−4 C/m2 and +5.3×10−4 C/m2 , respectively. In addition, assume that the material in the cell membrane has a dielectric constant of 5.5. Part A . Find the direction...

Camels require very little water because they are able to tolerate relatively large changes in their body temperature. While humans keep their body temperatures constant to within one or two Celsius degrees, a dehydrated camel permits its body temperature to drop to 34.0 ∘C overnight and rise to 41.0 ∘C during the day. Part A To see how effective this mechanism is for saving water, calculate how many liters of water a 420 kg camel would have to drink if...
