Question

Tausonite, a mineral composed of Sr, O, and Ti, has the cubic unit cell shown in the drawing. (a) What is the empirical formula of this mineral?

Accepted Answer

Hey everyone, we're told that barium tightening, it has a cubic unit cell, determine its empirical formula. If it is composed of barium, oxygen and titanium. Starting off with barium, we can see that we have eight corners of our cube, and on each corner we have that one barium. So we're going to multiply this by 1/8 adam per one corner. Now when we use our dimensional analysis we end up with a total of one barium adam. Now looking at our oxygen, we can see that oxygen occupies the center of the six faces of our cube. So we're going to get our six faces of the cube and we're going to multiply that by one half adam per one face. And when we calculate this out, we end up with a total of three oxygen atoms. Now looking at our titanium, we can see that we have one titanium atom at the center of our cube. So this means our empirical formula is going to come up to BATI 03 since we had one of barium, one of titanium and three of oxygen. And this is going to be our final answer. Now, I hope that made sense. And let us know if you have any questions
