Tungsten is a very high density, high melting point, and hard metal. These properties arepartially due to its body centered cubic (BCC) crystal structure. Tungsten has an atomicnumber of 74 and an average mass of 183.8u. (1u = 1.661x10-27 kg). X-ray diffractionexperiments determine that the Bravais lattice has a characteristic length of 3.155 Å (Thismeans each side of the cube shown below has a length of 0.3155 nm.)How many complete tungsten atoms are there in each BCC unit cell?

My physics class has turned to online due to the COVID-19 and I am having trouble with some of the word problems my teacher gave me to work on. She presented me with: I am contemplating a career change. If I had 500g of stolen gold jewelry, how much energy would I have to add to it to melt it (so that it was not longer recognizable)? Pretend that it is pure gold. Would you be able to show me how to accomplish this problem so I can see the steps? Thank you for your time. John Payton
