To calculate the relative atomic mass of chlorine, we need to take into account the mass numbers of its isotopes and their relative abundance.

Step 1: Convert the percentages into decimals.
75% = 0.75
25% = 0.25

Step 2: Multiply the mass number of each isotope by its relative abundance.
For the isotope with a mass number of 34: 34 * 0.75 = 25.5
For the isotope with a mass number of 39: 39 * 0.25 = 9.75

Step 3: Add these values together to find the relative atomic mass.
25.5 + 9.75 = 35.25

So, the relative atomic mass of chlorine is 35.25.
