Atomic mass of nitrogen is 14.0067 u. find out the mass of onee nitrogen atom (up to 3 significant figures).

Text Solution

Verified by Experts

Mass of `6.022xx10^(23)` no. of N-atoms=14.0067g
`therefore`Mass of 1 N-atom`=(14.00674)/(6.022xx10^(23))g=2.3259xx10^(-23)g`
`=2.32xx10^(-23)g`
[After rounding off up to 3 significant figures].
