The energy released by 1 atom of Uranium is Q=185.*10^6-25.
The energy needed for U.S. that I will name Q2, in eV is: 1*10^19J* (1eV/(1.602*10^-19))=6.2422*10^37eV
Q=mc^2
Q2=mc^2
m is the mass of Uranium in kg that we calculated at 3.90*10^-25. We need to fund m2 because that is the unknown mass in the equation for Q2 to give us the energy for the U.S. and remember, Q is the energy that 1 atom of Uranium gives out which is why we took a ratio.
m2=Q2/Q*m=1.3*10^5 kg (final answer)
Answer:
A particle is the smallest possible piece of something, of matter, while a molecule is the smallest particle of an element, for example H2 is molecule, smallest particle of the hydrogen in the air, and the molecule is two or more atoms held with chemical bonds, and have chemical properties.
Hence molar mass (M) of Magnesium Chloride; MgCl.= M (2Cl)+M (Mg) = 70.90+24.31=95.21 g/mol.
