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 fractions.
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 30: 30 * 0.75 = 22.5
For the isotope with a mass number of 38: 38 * 0.25 = 9.5

Step 3: Add these values together to find the relative atomic mass.
22.5 + 9.5 = 32

So, the relative atomic mass of chlorine is 32.
