Determine the mass of 1 F-atom in gramm (F-19).

Text Solution

Verified by Experts

Gram-atomic mass of fluroine=19g.
`therefore`The mass of 1 gram-atom of fluorine=19g
Number of atoms in 1 gram-atom of fluorine=`6.022xx10^(23)`
`therefore`Mass of `6.022xx10^(23)` atoms of fluorine=19 g
hence, the mass of 1 atom of fluorine`=(19)/(6.022xx10^(23))g`
`=3.1550xx10^(-23)g`.
