a. Uru is a metal ore from the first moon, and it also appears to have metallic properties. The appearance of Urw metal ore is in two forms, one as "metallic gold" and the other as having a luster that has been described as "badly wrought iron." One of this form crystallizes in a body-centered cubic unit cell with an edge length of 2.201x10 cm, and approximate density of 7.87 g/ml. Avogadro's number = 6.022x1023 per mol. а.1. Draw the unit cell bcc and label the position of its lattice points. а.2. How many atoms contribute per unit cell of bcc? а.3. Determine the molar mass of this metal. а.4. Based on your calculations, which among the two forms of Uru is this metal?

a. Uru is a metal ore from the first moon, and it also appears to have metallic properties. The appearance of Urw metal ore is in two forms, one as "metallic gold" and the other as having a luster that has been described as "badly wrought iron." One of this form crystallizes in a body-centered cubic unit cell with an edge length of 2.201x108 cm, and approximate density of 7.87 g/ml. Avogadro's number = 6.022x1023 per mol. а.1. Draw the unit cell bcc and label the position of its lattice points. а.2. How many atoms contribute per unit cell of bcc? а.3. Determine the molar mass of this metal. а.4. Based on your calculations, which among the two forms of Uru is this metal?
