confusing chemistry question

confusing chemistry question

Fringe_Agent13

Using the values for mass of hydrogen and chlorine-35 given in questions 4 and 6 on page 7 of the handout, what is the reduced mass of the H35Cl molecule in kilogram to 3 significant figures (use notation: X.XX E XX to input the answer).

The mass for Hydrogen from question 4 is confusing. I'm given m subscript 1H = 1.007825 and m subscript 2H = 2.01400 amu while the mass for 35 Cl is given as 34.969 amu.
