Question

The mass of 7 N15 is 15.00011 amu, mass of 8 O16 is 15.99492 amu and mP =1.00783 amu. Determine binding energy of last proton of 8 O16 (A) 2.13 MeV (B) 0.13 MeV (C) 10 MeV (D) 12.13 MeV

Tardigrade Admin · Accepted Answer

M( 8 O16)=M( 7 N15)+1 mp binding energy of last proton =M(N15)+mp-M( 1 O16) =15.00011+1.00783-15.99492 =0.01302 amu =12.13 MeV

Q. The mass of $_{7} N^{15}$ is $15.00011$ amu, mass of $_{8} O^{16}$ is $15.99492$ amu and $m P = 1.00783$ amu. Determine binding energy of last proton of $_{8} O^{16}$

2.13 MeV

0.13 MeV

10 MeV

12.13 MeV

$M (_{8} O^{16}) = M (_{7} N^{15}) + 1 m_{p}$
binding energy of last proton
$= M (N^{15}) + m_{p} - M (_{1} O^{16})$
$= 15.00011 + 1.00783 - 15.99492$
$= 0.01302 am u = 12.13 M e V$
