Question

Calculate energy equivalent of 1 g of substance .​

Answer 1

Step-by-step explanation:

If you're looking to find how much energy is in one gram of a given substance with mass, disregarding some math, just take mass and multiply it by c^2. So m = 1g = 0.001kg, E = mc^2 = (0.001kg)(299792458m/s)^2 = 8.987551787E13kgm^2/s^2 = 8.99 x 10 ^ 13 joules.

Answer 2

Given

m = 1g = 10^-3 kg

we know that is speed of light = 3*10^8m/s

Noe

E = mC^2

E = 10^-3(3*10^8)^2

E = 9 *10^13joule
