Answer: 0.001 metric tonnes

Explanation:

According to Einstein equation, Energy and mass are inter convertible.

$E=mc^2$

E= Energy

m = mass

c= speed of light

Given : Complete combustion of 1.00 kg of coal releases about $3.0\times 10^7 J$ of energy.

Given mass: 1 kg

Converting kg to metric ton using the conversion factor:

1 kg=0.001 metric tonnes

Thus 1 kg of coal would also be equal to 0.001 metric tonnes.
