vaporised sample B 25Mg electromagnet chart recorder b) Write an equation to show the ionisation of Mg in a mass spectrometer. Magnesium has three stable isotopes. The following table shows the relative abundance in a naturally occurring sample of magnesium: Natural abundance % Isotope 24Mg Kaplan International Pathways to vacuum pump 23.9850 amplifier Relative mass 24.9858 25.9826 78.99% 10.00% 26Mg c) Use the data in the table to calculate the relative atomic mass of the magnesium sample. (2 ma (3 ma 11.01% d) Sketch the mass spectrum for a sample of magnesium. (4 ma e) Magnesium is the most commonly used element in Group 2. Magnesium nitrate appears as a white crystalline solid, it decomposes to produce solid magnesium oxide, toxic nitrogen dioxide and oxygen gas at a temperature of over 300C. Write and balance this reaction equation, including their states. (3 ma kaplanpathways.co
