Consider the root mean square end-to-end distance using the valence angle model with hindered rotation. For polymer A and polymer B, the fixed bond angle () is the same for both polymers. However, polymer A's steric parameter is 5 times larger; it has 4 times the number of bonds; and each bond is 6 times longer. How many times larger is the root mean square (not mean square) end-to-end distance of polymer A? Round to the nearest tenth (one place after the decimal point)
