A certain sample of element Z contains 60% of 69Z and 40% of 71Z. What is the relative atomic mass ofelement Z in this sample?A. 69.2B. 69.8C. 70.0D. 70.2
Question
Solution 1
To calculate the relative atomic mass of element Z, we need to take into account the percentage of each isotope and their respective atomic masses.
Step 1: Convert the percentages into proportions. 60% becomes 0.60 and 40% becomes 0.40.
Step 2: Multiply the atomic mass of each isotope by its pro Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
