Calculate the unit cell edge length for an 85 wt% fe-15 wt% v alloy. all of the vanadium is in solid solution, and, at room temperature the crystal structure for this alloy is bcc

Answer is 0.289nm.

Explanation: The wt % of Fe and wt % of V is given for a Fe-V alloy.

wt % of Fe in Fe-V alloy = 85%

wt % of V in Fe-V alloy = 15%

We need to calculate edge length of the unit cell having bcc structure.

Using density formula,

For calculating edge length,

For calculating , we use the formula

Similarly for calculating , we use the formula

From the periodic table, masses of the two elements can be written

Specific density of both the elements are

Putting   and formula's in edge length formula, we get

By calculating, we get

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

i think its 100

i hope this !
