Right Meshack, let's go. Step 1: Identify the mass numbers and their percentage abundances from the graph. • Isotope 1: Mass number = 204, Percentage abundance = 1.5% • Isotope 2: Mass number = 206, Percentage abundance = 23.6% • Isotope 3: Mass number = 207, Percentage abundance = 22.6% • Isotope 4: Mass number = 208, Percentage abundance = 52.3% Step 2: Use the formula for relative atomic mass. The relative atomic mass is calculated as the sum of (isotope mass $\times$ fractional abundance) for all isotopes. $$ \text{Relative atomic mass} = \sum (\text{isotope mass} \times \frac{\text{percentage abundance}}{100}) $$ Step 3: Substitute the values and calculate. $$ \text{Relative atomic mass} = (204 \times \frac{1.5}{100}) + (206 \times \frac{23.6}{100}) + (207 \times \frac{22.6}{100}) + (208 \times \frac{52.3}{100}) $$ $$ \text{Relative atomic mass} = (204 \times 0.015) + (206 \times 0.236) + (207 \times 0.226) + (208 \times 0.523) $$ $$ \text{Relative atomic mass} = 3.06 + 48.596 + 46.782 + 108.784 $$ $$ \text{Relative atomic mass} = 207.222 $$ The relative atomic mass of lead is 207.222. $$ \boxed{207.222} $$ Send me the next one 📸
