Web22 de mar. de 2024 · The resolving power, or resolution, of a mass spectroscope is a measure of its ability to separate adjacent masses that are displayed as peaks on the detector. If two peaks due to mass m and (m + Δm) can just be separated, the resolving power is m/Δm.The early machines had resolving powers of only a few hundred. In 1935 … WebThe total mass of these would be (23 x 10) + (100 x 11) = 1330 The average mass of these 123 atoms would be 1330 / 123 = 10.8 (to 3 significant figures). 10.8 is the relative atomic mass of boron. Notice the effect of the "weighted" average. A simple average of 10 and 11 is, of course, 10.5.
