Question

Calcium crystallizes in a face-centered cubic unit cell at 
room temperature that has an edge length of 5.588 Å. 
(b) Calculate the density of Ca metal at this temperature.

Accepted Answer

Hi everyone. So ask calculate the density of nickel metal. If it crystallizes in a face centered cubic unit cell, it has an edge length of 3.5-4 angstrom. So for a face centered cubic unit cell, the density Is equal to four. Similar mass by by the edge length. You times avocados number. The density is what we're looking for. The miller mass. 58.69 grams. Promote average joe's number. This is 6.02, 2 times 10-23 Adams. And for the edge length we need to convert this 2cm 3.5 - four. Thanks shrimp. And in one and jump We have one times 10 to negative eight cm. They get 3.5 - four. I'm sent to negative 3 -8 centimeters. So now if you guys are gonna get the density equals £ 58.69 g per mole By 3.5 to 4 potential negative eight centimeters. Cute. I'm 6.02. 2 times 10-23 Adams. You get 8.91 g per centimeter cubed.
