Problem 150 Hard Difficulty

Suppose you are given a cube made of magnesium (Mg) metal of edge length $1.0 \mathrm{cm}$. (a) Calculate the number of Mg atoms in the cube. (b) Atoms are spherical in shape. Therefore, the Mg atoms in the cube cannot fill all of the available space. If only 74 percent of the space inside the cube is taken up by Mg atoms, calculate the radius in picometers of a Mg atom. (The density of Mg is $1.74 \mathrm{g} / \mathrm{cm}^{3}$ and the volume of a sphere of radius $r$ is $\frac{4}{3} \pi r^{3}$.)

the given information is scenes scenes. One more love McNish Youm condemns 6.2 into 10. Dress to dip over 23 atoms is the number off it comes in a cube is Q B's. So the number off Adams is he will do in into 6.0 to multiply. 10. Dress to dip our 23 atoms, but a more you see well, too. Seven 0.16 into 10. Race to the powers to minus two mall into 6.0 through multiple light and rest with the power granted three atoms Let him on is equal to 4.31 in tow. 10. Race to the power 22 Adams and given information for but be scenes Atoms are it Comes, uh, see for ago. They dig up 74% offi cubes space we have to find they rarely use in Be commuters off ignition. Adam. So the will you off, Adam is Will you move? Adam is it will do 74% into volume. Divided by the number off Adams is it will do 74 person into one point. Zito, you big some divided by four point number of items are 4.31 into 10. Dress to the power 22 atoms is equal to is equal to We have 17. 17 blind 17 into 10 raised to the power minus 24 cubic centimeter for it, um, into one point, then went into 10 raised to the power 30 become inter cube, divided by 1 cc, is equal to 17.17 into 10. Race to the power six pick a meter cube and the reduce off ignition system is volume off. Item is able to four but she by our CUC William of it, um is equal to four by three by our cube. Are you busy? Well, too William of it, um, into three body before she reminded by by music able to 17 point and 17 into 10 dressed with the power six. He commuter cube into a tree by four divided by value of pIease 3.14 is equal to 4.99 into 10. Race to dip our six, the commuter cube. So our is equal to undeterred cube four point 099 into Henry's to re power. Six people meted Cube is equal to we have 1 60 decommitted so he had defined in prison for is four point.
