A 3,65 kg mass attached to a light string rotates on a
horizontal, frictionless table. The
radius of the circle is 1.21 m, and
the string can support a mass of
32.4 kg before breaking. The
acceleration of gravity is
9.8m/s2. What maximum
speed can the mass have before
the string breaks?

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
