Try to solve the following question.

(a)   Some hypothetical metal has a simple cubic crystal structure. If its atomic weight is 70.4 g/mol and the atomic radius is 0.126 nm, estimate its density.

Please share your final answer in the comment section. I would like to see how many of you try this out.

you may try this question too

The unit cell volume for a certain element with  unit cell parameters x=0.6 nm and y=0.3 nm can be calculated using the following formula:

Vc = x²y

The atomic radius of this element is 0.16 nm, the atomic weight is 115.4 g/mol and the density is 7.1 g/cm³. With these data and the above formula, compute the atomic packing factor for this element.

dont forget to share your answer in the comment section.
