For the indicated carboxylate arm in the supplied WP6 charge-state model, what is the C20-O22 bond length? Report the length in angstrom to three decimal places.

Use the supplied complete 150-atom WP6 XYZ attachment (asset S0005). Coordinates are in angstrom. Atom rows are numbered from 1 after the two header lines; a physical file line number is atom row + 2. Use this one supplied conformer without relaxation. Labels C1, C3, etc. below mean element plus XYZ atom row, not unique original PDB atom names. Carbon C20 (row 20) is connected to the arm carbon C14 and to oxygens O22 and O24 (rows 22 and 24). The provided challenge model describes these arms as carboxylate groups. Measure only the selected C20-O22 bond. No assignment of its real solution protonation state is requested.
