10 am
Which of the following is the correct way to calculate the mechanical advantage of this wedge?
OA 10 cm - 38 cm = 0.26
OB. 38 cm - 10 cm = 3.8
C. 38 cm - 10 cm = 28 cm
OD 38 cm + 10 cm = 48 cm

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
