Astudent performed the experiment described in your lab handout. he used 4.972 grams of hydrogen peroxide and roughly 10 mls of 1.0 m ki and produced a 71.7 ml volume of gas. the experiment was preformed at 27oc.  the  atmospheric  pressure was 761.4 torr
what was the partial pressure (in torr) of water vapor in the 100 ml  cylinder? what was the partial pressure (in torr) of o2  in the 100 ml  cylinder? what was the partial pressure (in atm) of o2  in the 100 ml  cylinder? how many moles of o2  were produced? how many moles of h2o2  were consumed? what mass of h2o2  was consumed? what was the % by mass of h2o2  in the original solution?
