Calculate the energy equivalent of 1g of substance
Answer: To calculate the energy equivalent of 1g of a substance, you can use Einstein’s famous equation, E=mc^2, where E is the energy equivalent, m is the mass of the substance, and c is the speed of light in a vacuum, approximately equal to 3.00 x 10^8 m/s.
Given that the mass of the substance, m = 1g = 0.001kg (since 1g = 0.001kg), you can now plug in the values into the equation:
E = (0.001kg) x (3.00 x 10^8 m/s)^2
E = 0.001kg x 9.00 x 10^16 m^2/s^2
E = 9.00 x 10^13 joules
Therefore, the energy equivalent of 1g of the substance would be 9.00 x 10^13 joules. This calculation showcases the immense amount of energy stored in even small amounts of mass, as demonstrated by Einstein’s equation.
