2 CHEMISTRY-RELATIVE ATOMIC MASSthe mass of a hydrogen atom 1/1H is equal to 1/12 of the mass of a carbon-12 atomso its relative isotopic mass is 1.A magnesium atom 24/12Mg is twice as heavy as a carbon-12 atom,so its relative isotopic mass is 24再给另一个例子不要用英文角度解释...

More Commonly Known as Relative Atomic Mass Atomic massis used interchangeably with atomic weight, although the two terms don't mean precisely the same thing. Another issue is that "weight" implies a force exerted in a gravitational field, which would be measured in units of force, like newtons...
The relative uncertainty or relative error formula is used to calculate the uncertainty of a measurement compared to the size of the measurement. It is calculated as: relative uncertainty = absolute error / measured value If a measurement is taken with respect to a standard or known value, calcu...
