Transcribed Image Text:Aluminum reacts with aqueous sodium hydroxide to produce hydrogen gas
according to the following equation:
2Al(s) + 2NAOH(aq) + 6H2O(1)2NAAI(OH)4(aq) + 3H2(g)
The product gas, H2, is collected over water at a temperature of 20 °C and a pressure
of 758 mm Hg. If the wet H2 gas formed occupies a volume of 6.62 L, the number of
moles of Al reacted was
mol. The vapor pressure of water is 17.5 mm Hg
at 20 °C.
A mixture of oxygen and helium gases, at a total pressure of 731 mm Hg, contains
6.32 grams of oxygen and 0.620 grams of helium. What is the partial pressure of
each gas in the mixture?
