306587 If isotopic distribution of C -12 and C -14 is 98% and 2% respectively, then the number of C - 14 atoms in 12g of carbon is

306588 An element X has the following isotopic composition:
\(^{{\rm{200}}}{\rm{X:90}}{{\rm{\% }}^{{\rm{199}}}}{\rm{X:8}}{\rm{.0}}{{\rm{\% }}^{{\rm{202}}}}{\rm{X:2}}{\rm{.0\% }}\)
The weighted average atomic mass of the naturally occurring element X is closest so

306589 Neon has two isotopes \(\mathrm{\mathrm{Ne}^{20}}\) and \(\mathrm{\mathrm{Ne}^{22}}\). If atomic weight of Neon is 20.2 , the ratio of the relative abundances of the isotopes is

306590 Assertion :
Mass spectrometer is used for the identification of isotopes.
Reason :
Isotopes are the atoms of same element differing in mass numbers.

306591 Boron has two stable isotopes, \(^{{\rm{10}}}{\rm{B}}\left( {{\rm{19\% }}} \right)\) and \(^{{\rm{11}}}{\rm{B}}\left( {{\rm{81\% }}} \right)\). The atomic mass that should appear for boron in the periodic table is
