Waec Model Questions Vol1 2020 Chemistry Question 1
Practice practical question 1 from the 2020 Waec Model Questions Vol1 Chemistry examination. This question covers Isotopes, Relative atomic mass, Mole concept, Mass spectrometry, Sources of experimental error .
A student uses a magnetic sector mass spectrometer to analyse a pure metallic element X. The mass spectrum shows two isotope peaks at mass numbers 35 and 37. The recorded peak areas are 3.0 × 10⁵ for the 35‑amu peak and 1.0 × 10⁵ for the 37‑amu peak. The student also weighs a 0.500 g sample of the same metal on an analytical balance. Using the spectrometric data, the student is required to determine the relative atomic mass of element X and the amount of substance in the weighed sample.
