Answer
there are to answers one is an answer to a problem or a mixture of chemicals
Explanation:
To calculate moles from grams using chemical formulas ... However, one mole of magnesium weighs 24.31 g. ... 0.873 g x 95.21 g = 9.17 x 10-3 mol MgCl2.
Energy and mass equivalence
Explanation:
The law of conservation of energy does not apply to nuclear reactions, the law of conservation of mass-energy makes more sense in this regard.
In nuclear reactions mass is transformed into energy. Therefore, it does not conform with the law of conservation of energy.
- According to the law of conservation of energy "energy is neither created no destroyed but they are transformed from one form to another. "
- In nuclear reactions, mass is usually lost. Mass is not conserved.
- But, the mass is converted into energy and we say there is mass and energy equivalence for nuclear reactions.
