Question

The density of lead is 11.35 gcm^–3 and the radius is found to be 174.7pm. Is lead unit cell a simple cubic, a body centered cubic or a face centered cubic structure?
Given atomic mass of lead is 207 grams per mole , Avagadro's constant= 6.022 x 10^23 mol^-1

Answer 1

Answer:

i am in 6th grade i learned this is 7th trough 9th grade wotk

easy

Explanation:

For fcc, r=a2√2=0.3535a=0.3535×494.3 pm=174.7pm ... Computer will find solution for you ... The density of lead is 11.35g cm-3 and the metal crystallizes with fcc unit cell. ... (At. Mass of lead = 207g mol-1 and NA=6.02×1023mol-1). ... If the radius of copper atom is 127.8 pm, is the copper unit cell a simple cubic
