In one molecule of CHCl3, what total mass do the chlorine atoms contribute if Cl = 35.45 amu?

1. The subscript 3 in CHCl3 shows three chlorine atoms per molecule. 2. Each chlorine atom has an average atomic mass of 35.45 amu. 3. The chlorine subtotal is 3 x 35.45 amu = 106.35 amu. 4. The figure 119.37 amu is the whole molecule, not just the chlorine share. _Source: OpenStax Chemistry (CC BY 4.0), Ch 3 "Composition of Substances and Solutions", section 3.1 Formula Mass and the Mole Concept_
