A rigid massless rod is rotated about one end in a horizontal circle. There is a mass attached to the center of the rod and a mass attached to the outer end of the rod. The inner section of the lord sustains 2.08 times as much tension as the outer section. Find the ratio of the mass attached to the outer end to the mass attached to the center.

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
