Iwill give brainliest. when a mole of lithium reacts chemically with hydrogen to form lithium hydride, the energy released is found to be roughly 90 joules. how much mass is lost? 1.0 x 10-15 kg 2.7 x 1010 kg 1.0 x 1015 kg 3.0 x 10-7 kg

Answer : The mass lost is,

Explanation :

According to the Einstein equation, the energy is equal to the product of mass and the square of the speed of light.

The mathematical expression is :

where,

E = energy  = 90 J =

c = speed of light =

m = mass = ?

Now put all the given values in the above formula, we get the amount of energy released.

Therefore, the mass lost is,
