1.2 Mass Spectra of Elements
BeginnerMCQGraphicalMathematicalConceptual17.2k
Draw a simple stick mass spectrum on a white background in grayscale. The horizontal axis is labeled \(m/z\) and has exactly two labeled tick marks, 35 on the left and 37 on the right. The vertical axis is labeled “relative abundance” and has tick labels 0, 1, 2, and 3 in arbitrary units. Include light horizontal gridlines at these four levels and no vertical gridlines. Exactly two narrow solid-black vertical peaks rise from the baseline at the corresponding horizontal positions: the left peak reaches 3 units, and the right peak reaches 1 unit. Use equal line widths for both peaks. Do not include a connecting curve, legend, isotope symbols, percentages, charge labels, or annotations. No other peaks, labels, text, or marks appear.
Mass spectrum of a natural chlorine sample
A student obtains a mass spectrum of a natural sample of chlorine after the atoms are ionized to form singly charged ions. The resulting spectrum is shown.

Based on the relative heights of the peaks, what is the estimated relative atomic mass of chlorine?
