How many grams of matter would have to be totally destroyed to run a 115 W lightbulb for 2 years? Mass of Matter: To compute the number of grams of matter, we have to compute the value of energy E from the general mathematical formula of power P shown be...
or simply u). It is defined to be equal to exactly one-twelfth the mass of an unbound carbon-12 atom. By definition, the mass of one mole of an element, or Avogadro's number (6.02 x 1023) of atoms, is equal to its atomic mass in grams. In ...
Simply add the relative masses of the constituent elements to find the relative mass of a molecule. This is easy to do if you know the relative atomic masses of the elements in question. For example, water has the chemical formula H2O, so there are two atoms of hydrogen and one atom of...
have a critical mass of fissionable U-235 in the reactor core, spontaneous fission will result. It doesn't matter how close together the atoms are. If they're too close together, then you get an uncontrolled chain reaction and a nuclear explosion. You don't want that in a power plant....
