The volume of a gas is 550 mL at 960 mm Hg and 200.0 C. What volume would the pressure of the gas be 830 mm Hg if the temperature is reduced

to 150.0C? Make sure your answer is rounded to nearest whole number

and your final answer has the units of mL. *

Calculate the ratio of h+ ions to oh– ions at a ph = 7. 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 = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
