You order a 16 oz glass of tea (where the mass of water is 474 grams) from a local restaurant. the tea is freshly brewed and has an initial temperature of 21.39 °c. you add ice to cool it. if the heat of fusion of ice is 6.020 kj/mol and each ice cube contains exactly 1 mol of water (assume the ice does not add anymore volume), how many ice cubes are necessary to cool the tea to 1.59 °c? the specific heat of the "tea" is 4.184 j/g°c.

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
