Chapter 1, Problem 7P
A crystalline solid consists of atoms stacked up in a repeating lattice structure. Consider a crystal as shown in Figure P1.7a. The atoms reside at the corners of cubes of side L = 0.200 nm. One piece of evidence for the regular arrangement of atoms comes from the flat surfaces along which a crystal separates, or cleaves, when it is broken. Suppose this crystal cleaves along a face diagonal as shown in Figure P1.7b. Calculate the spacing d between two adjacent atomic planes that separate when the crystal cleaves.

7. A crystalline solid consists of atoms stacked up in a repeating lattice structure. Consider a crystal as shown in Figure P1.7a. The atoms reside at the corners of cubes of side L 5 0.200 nm. One piece of evidence for the regular arrangement of atoms comes from the flat surfaces along which a crystal separates, or cleaves, when it is broken. Suppose this crystal cleaves along a face diagonal as shown in Figure P1.7b. Calculate the spacing d between two adjacent atomic planes that sep- arate when the crystal cleaves.
The density of platinum is 21.45 x 103 kg/m3.
a. Calculate the volume (in m3/atom) occupied per platinum atom
b. Estimate the atomic diameter (in m);(The estimate uses the approximation that it is a cubic volume)
c. Using this estimation, calculate the thickness of a metal foil (in m) containing 2.0 x 101 atomic layers of platinum.

- A simple physics formula is density equals mass divided by volume. In problem 2 above, the density was δ(x,y,z) = e^((x^2+y^2+z^2)^3/2).The volume of the object could be calculated from the equations for volumes of spheres and cones with some simple subtraction. Why do we need to do a triple integral to find the mass of the solid? Why can’t we just use the physics formula M = ρ ·V ? Explain when we need a triple integral to calculate mass, and when we can get away with the simple physics formula. Most importantly, explain how the triple integral of p*dV uses the same physics formula and explain what the idea of an integral means.arrow_forwardC L You are tasked with specifying the following structure.
