1. Metallic strontium crystallizes in a face-centered cubic lattice, with one Sr atom per lattice point. If the edge length of the unit cell is found to be 608 pm, what is the metallic radius of Sr in pm? 2. The substance beta manganese is found to crystallize in a cubic lattice, with an edge length of 630.0 pm. If the density of solid beta manganese is 7.297 g/cm3, how many Mn atoms are there per unit cell?

Explanation:

From the question we are told that:

Edge length of the unit cell

a)

Generally the equation for The relationship between edge length and radius is mathematically given by

Therefore

b)

From the question we are told that:

Density

Edge length of

Therefore Volume  is given as

Generally the equation for Mass is mathematically given by

Therefore Molarity is given as

Finally The atoms in a unit cell is

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

no but i do not usually comment or use my voice that much when it comes to social media
