Web25 aug. 2024 · Multiply the exact mass of each isotope by its corresponding mass fraction (percent abundance ÷ 100) to obtain its weighted mass. Add together the weighted masses to obtain the atomic mass of the element. Check to make sure that your answer makes sense. Solution: WebTogether, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the … WebStep 1: Multiply the atomic mass of the isotope with its abundance percentage and divide the result by 100. Step 2: Add the values gained from step 1 for each given isotope in the sample.

The preponderance of sulfur-32 is explained by its production from carbon-12 plus successive fusion capture of five helium-4 nuclei, in the so-called alpha process of exploding type ... is melanoma a blood cancer

"WebWe start by multiplying each isotopes’ mass by its abundance. This can be done in two ways. First, we can directly multiply the mass by the percent: 23.985 amu (78.70)= 1887.6 amu On the other hand, we can change the percent to a decimal out of one and then multiply by the mass. This can be done by dividing the percent by 100. " - How to calculate isotopic mass
