Question

an element with molar mass 27 gm forms a cubic unit cell with edge length 4.05× 10^ -8 cm if it's density is 2.7 g cm ^ -3 what is the nature of the cubic unit cell​

Answer 1

ANSWER IS Z= 4. VOTE Me Complete step by step answer: It is given that the molar mass of the element is 27 gmol−1, the edge length of the cell is 4.05×10−8cm. The density is 2.7 gcm−3. 4.05×10−8cm = 4.05×10−10m.
