In relation to Question 16, why does the fraction in the worked solutions have to equal 1?



If you and I finish a pizza together, if you add up the % you ate with my %, it must equal 100%. Likewise, if you add up the fraction of the pizza that you ate and my fraction, it must add to 1 (GM 1.4, fractions and percentages). So if there are only 2 isotopes that make up the final product, then those isotopes add to 100%, or as fractions, they add to make the number 1.
