Question

Lithium metal has body centred cubic lattice structure with its length of 352pm calculate the density of lithium metal at mass of 7 gram per mol n a = 6.022 into 10 to the power 23 atoms mole

Answer 1

Answer:

what is your questions I can't understand

Answer 2

Answer:

density= z×molar mass of lithium/(length in cm)^3 × avagadro number ,, z=2 for bcc and molar mass =7 edge length is 353×10^-8 cm putting the value and got your ans hope it may help you
