Titanium (ti) has an hcp crystal structure, a density of 4.51 g/cm3, and the atomic weight for ti, ati= 47.9 g/mol.(a)what is the volume of its unit cell in cubic meters? (b)if the c/a ratio is 1.58, compute the values of cand a.

(a)

(b)

Explanation:

Hello,

(a) In this case, we apply the following formula in order to solve for the volume per unit cell, :

Now, a accounts for the atoms into the HCP which are 6, M accounts for the atomic mass of titanium and for the Avogadro number, thus:

(b) Here, for the HCP:

We know that and , thus:

Best regards.

answer; ///i do believe that the correct answer is (b); ///particle composed of two or more atoms bonded together;

indium, and thallium have three electrons i think
