The density of iron is `7.87g//cm^(3)`. If the atoms are spherical and closely packed. The mass of iron atom is `9.27xx10^(-26)kg`. What is the volume of an iron atom?

Options

A. `1.18xx10^(-26)m^(3)`
B. `2.63xx10^(-29)m^(3)`
C. `1.73xx10^(-28)m^(3)`
D. `0.53xx10^(-29)m^(3)`

Explanation

(a) Volume `=("mas")/("density")=(9.27xx10^(-26)xx10^(-3)g)/(7.87g//cm^(3))`
`=1.18xx10^(-29)m^(3)`
