Question

The density of irridium is 22.4/cm3.The unit cell of irridium is FCC calculate the radius of irridium atom. molar mass of irridium is 192.2g/mol


pls answer this question​

Answer 1

Answer:

1.26998731 cm

Explanation:

Here, M=192.2g/mol, p=22.4/cm3

M= p×V

V= M/p= (192.2 / 22.4)= 8.58 cm3

V= (4/3)πR^3

R= [V/(4/3)π]^(1/3)

=[8.58/(4/3)π]^(1/3)

=1.26998731 cm
