Question

In the decomposition of Po-211 to form a daughter nuclide, the mass defect = 6.67 x 10-25 kilograms. If all of this �lost mass� is converted to energy, what would the value be in joules? (1 J = 1 kg m2/s2)


2.22 x 10-17 J

3.00 x 10-12 J

6.00 x 10-8 J

7.41 x 10-15 J

Answer 1

Please Help!

Answer 2

E=mc^2

Answer 3

energy released E=mc^2

where m=mass defect,c=speed of light,(3X10^8 m/s)

Answer 4

the answer is option c.
