Mass of atoms chart
WebUnits of measure have been defined for mass and energy on the atomic scale to make measurements more convenient to express. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams. Besides the standard kilogram, it is a second mass standard. WebChapter 3 Practice Problems Name _ Part 1 1.
