5. Calculate the atomic mass of Iron just like you did for M8Mium. The following are the known isotopes for iron: (show all work) Fe-54-5.945% Fe-56-91.85% Fe-57-2.03% Fe-58-0.282%

# Explanation:## Step1: Identify Isotopes and Their Abundances### List the isotopes of iron and their respective natural abundances: (5.945%), (91.85%), (2.03%), and (0.282%).## Step2: Convert Percentages to Decimal Form### Convert the given percentages to decimal form by dividing each by 100: ## Step3: Multiply Each Isotope's Mass by Its Abundance### Calculate the contribution of each isotope to the atomic mass by multiplying the mass number by the decimal abundance: ## Step4: Sum the Contributions### Add the contributions of each isotope to find the total atomic mass: # Answer: ### The atomic mass of Iron is approximately 55.966 amu.
