To calculate the relative atomic mass of chlorine, we use the weighted average of the masses of its isotopes, taking into account their natural abundances. Step 1: Identify the isotopic masses and their percentage abundances. • Chlorine-35 has an isotopic mass of 35 and an abundance of 75%. • Chlorine-37 has an isotopic mass of 37 and an abundance of 25%. Step 2: Convert percentage abundances to fractional abundances. • For Chlorine-35: (75)/(100) = 0.75 • For Chlorine-37: (25)/(100) = 0.25 Step 3: Apply the formula for relative atomic mass. The relative atomic mass is calculated as: Relative Atomic Mass = (isotopic mass × fractional abundance) Step 4: Substitute the values and calculate. Relative Atomic Mass = (35 × 0.75) + (37 × 0.25) Relative Atomic Mass = 26.25 + 9.25 Relative Atomic Mass = 35.5 The relative atomic mass of chlorine is 35.5. 35.5 Drop the next question 📸
