WebThe percentage of abundance and isotopic mass is used to calculate the average isotopic mass. For example, two isotopes of Nitrogen are N-14 and N-15 and the average … WebTo work out relative atomic mass, multiply the mass of each isotope by its relative abundance. Then add those numbers together and divide by the sum of the relative abundances. The calculation for working out the relative atomic mass of chlorine is: (25%x37) + (75%x35) = 9.25 + 26.25 =35.5 Therefore, the relative atomic mass of …

GCSE Chemistry – Relative Atomic Mass 2. Work out x. All percentages = 100, so x = 100- (50+35) =15% 3. Form an equation for y. Use the given atomic mass and the equation for calculating it. 16.65 = (800 + 595 + 15y) / 100 4. Rearrange to find y. WebRelative atomic mass can be calculated by multiplying the isotope abundance times the isotope mass for each isotope of that element and adding the resulting values. To simplify the calculations, the mass number of an isotope is often used in place of the mass. brother laser toner cartridges tn310
