Step 1: Set up the equation for the relative atomic mass. Let x be the percentage abundance of ^63Cu. Then the percentage abundance of ^65Cu will be (100 - x). The relative atomic mass is calculated as: Relative Atomic Mass = (mass of isotope 1 × abundance of isotope 1) + (mass of isotope 2 × abundance of isotope 2)100 Substitute the given values: 63.55 = ((63 × x) + (65 × (100 - x)))/(100) Step 2: Solve the equation for x. Multiply both sides by 100: 63.55 × 100 = 63x + 65(100 - x) 6355 = 63x + 6500 - 65x Combine the x terms: 6355 = 6500 - 2x Subtract 6500 from both sides: 6355 - 6500 = -2x -145 = -2x Divide by -2: x = (-145)/(-2) x = 72.5 Step 3: State the percentage abundance. The percentage abundance of the ^63Cu isotope is 72.5\%. The percentage abundance of the ^63Cu isotope is 72.5%. What's next?
