Assume that a viral DNA molecule is a 11-μm-long strand with a uniform 20-Å diameter. Assuming complete flexibility of the molecule, will it fit inside a viral head that is a 8×10−2-μm-diameter sphere? Part A)What is the volume of the viral head in cubic angstrom (Å3)? Hint: Recall that the volume of a sphere can be calculated using this formula: Volume= (4/3) x pi x r2, where r stands for radius of the sphere. Also note that 1Å=0.1 nm. Express...

If the radius of a platinum atom is 1.3873 Å, what is the volume of the unit cell (in cm^3) if platinum has a FCC arrangement. Hint 1 Å = 1 x 10^-10 m. (Please write out all steps. I watched a video on the topic but I need clarity)
the diameter of an atom and write the value here in terms of both meters and nanometers. Aluminum foil has a thickness of 2.86 *10^-3 cm. Assuming the aluminum atoms stack directly on top of each other, use your answer for the diameter of an atom from question #1 to figure out how many atoms stack on top of each other in a sheet of aluminum foil.
A cube made of platinum (Pt) has an edge length of 1.50 cm. The density of Pt is 21.45 g/cm3. (a) Calculate the number of Pt atoms in the cube. (b)Atoms are spherical in shape. Therefore, the Pt atoms in the cube cannot fill all the available space. If only 74.0 percent of the space inside the cube is taken up by Pt atoms, calculate the radius in picometers of a Pt atom. The mass of a single Pt atom...
