Chapter 2: Q24.76P (page 40)

Arsenic-decays with an energy of1.57脳10- 15kJper nucleus. Convert this energy into

(a) eV;

(b) MeV.

Short Answer

Expert verified

补)9.80脳106eVb)9.80MeV

Step by step solution

01

Step 1:

-1MeV = 106eV

-1MeV = 1.602脳10- 13J

-1eV = 1.602脳10- 19J

(a)

We have to convert1.57脳10- 15kJinto electron volts.

1.57脳10- 15kJ=1.57脳10- 15办闯脳1000J1kJ脳1eV1.602脳10- 19J=9.80脳106eV

(b)

We have to convert 1.57脳10- 15kJinto electron volts.

1.57脳10- 15kJ=9.80脳106别痴脳1MeV106eV=9.80MeV
