1. The problem statement, all variables and given/known data r-bond length (in anströms) q-charge (in debyes) CO2 r(CO)=1.1867 q(C)=1.1352 q(O)=-0.5676 angle between them is 120 deg 2. Relevant equations 3. The attempt at a solution I know I have to make vectors and then add them, but I dont know how to make the vectors. I know the angle in CO2 is 180, just need to find the dipole moment if the angle was 120.
