In a nuclear reaction, the energy released is equal to 8.1 x 1016 joules. Calculate the mass lost in this reaction. (1 J = 1 kg m2/s2)

7.2 x 1032 kg

2.7 x 108 kg

9.0 x 10-1 kg

7.2 x 10-16 kg

What is the Question?

nvidiaintely · Answer

Chemistry.

da01159 · Answer

so 7.2 is what unit

nvidiaintely · Answer

kg

kevin · Answer

Have you calculate it @NvidiaIntely

kevin · Answer

I got

E = m x c^2
8.1 * 10^16 = m * (3*10^8)^2

m = 1.11

Idk if I calculate it wrong

kevin · Answer

Maybe we can go to another question while waiting for other response. lol

nvidiaintely · Answer

hmmm..
Well let me check Brainly.

Here:
Use the formula E=mc^2
energy given=8.1 x 10^16 joules
speed of light = 3.00 × 10^8 m/s

plug in the values we'll get mass=9.0 x 10-1 kg

Again no explaining...

kevin · Answer

Ok, than it will be 9.0 x 10-1 kg

nvidiaintely · Answer

Yeah, okay then next question...
