In 1 kilogram of pure water, the mass of hydrogen atoms is approximately 112 grams, or 0.112 kilograms. What is the energy equivalent of this mass in joules?

Verified Answer :

Using Einstein’s famous equation, E = mc^2

Given mass, m = 0.112 kg and knowing c = 3.0 x 10^8 m/s,
energy E can be determined

E = (0.112 kg)(3.0 x 10^8 m/s)^2

 = 1.008 x 10^16 J

Hope this helps

 

 

Answer:

\(1.008\times 10^{16}\) Joules is the energy equivalent of this .

Explanation:

Mass of hydrogen atoms in 1 kg of water = 112 g= 0.112 kg

Mass and energy related together and that expression was given by the famous scientist named Albert Einstein:

\(E=mc^2\)

E = Energy related to mass m

c = Speed of the light

m = 0.112 kg , c = \(3\times 10^8 m/s\)

\(E=0.112 kg\times (3\times 10^8)^2=1.008\times 10^{16} J\)

\(1.008\times 10^{16}\) Joules is the energy equivalent of this .
