How many atoms are in a cube
WebA cube made of platinum (Pt) has an edge length of 1.0 cm. (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 percent of the space inside the cube is taken up by Pt atoms, calculate the radius in picometers of a Pt atom. WebLook at the figure in below and answer these question according to it. a) How many atoms does this cubic structure have? (5 points) b) How many r length equals to the a length? Please calculate with showing in the figure. (10 points) c) Calculate the atomic packing factor (APF). (10 points) d) Calculate the density of this structure (g/m3).

WebIn a simple cubic lattice, the unit cell that repeats in all directions is a cube defined by the centers of eight atoms, as shown in Figure 4.1. 4. Atoms at adjacent corners of this unit cell contact each other, so the edge length of this cell is equal to two atomic radii, or one … WebThe energy provided by the Sun fuels many important processes on Earth. However, these are largely confined to Earth’s surface. The temperature in Earth’s core is about 7,000 o C (12,500 o F), or about 25 times hotter than the maximum temperature of your home oven. The temperature of space is about - 270 o C (-450 o F). From this ...
