C12H22011 (s) → 12 Cs) + 11 H2O(g) (a) When sucrose is heated, it decomposes into solid carbon and
water vapor. If 3.98 g of water vapor is collected from this
reaction, how many moles of water vapor were produced? Use
stoichiometry to show your work.
(b) The water vapor is collected at 21.0°C in a 1500.0 mL
container. Calculate the pressure of the water vapor. (4.7)
(c) If the gas collected is placed into a larger 2000.0 mL container,
what would the new pressure of the gas be? Assume that the
temperature and number of moles stays constant. (4.8)
