The volume of one atom of a metal M is 1...

The volume of one atom of a metal M is `1.66xx10^(-23)cm^(3)`. Find the atomic mass of M (given: density of M=2.7`g*cm^(-3)`).

Text Solution

Verified by Experts

Volume off `6.022xx10^(23)` atoms of the metal, M
`=6.022xx10^(23)xx1.66xx10^(-23)=9.99652cm^(3)`
`therefore`Mass of `6.022xx10^(23)` atoms of the metal M
=density`xx`volume=2.7`xx9.99652=26.990g`
=gram-atomic mass of the metal M
Hence, atomic mass of the metal=2.990.
