The ratio Cu63/Cu65 for bulk or commercially processed copper is very near the value of 2.2440, and the atomic weight of such copper is 63.5455卤0.0010. The causes of the natural variations in copper abundance ratios are not known. Unless otherwise stated the indicated uncertainties are over-...
Only two isotopes of copper occur naturally, 63Cu( atomic mass = 62.9296 amu; abundance 69.17%) and 65Cu(atomic mass = 64.9278 amu; abduance 30.83%). Caluclate atomic weight average atomic mass of copper. True or false? An...
