An gas sample contains 5.93% argon.  If the total pressure is [Pt] mmHg, what is the partial pressure of argon (in mmHg)?

Dinitrogen monoxide (also called nitrous oxide) is used as a propellant gas for whipped-cream dispensers (and you thought chemistry was not relevant to you!!). Dinitrogen monoxide and water are formed when ammonium nitrate is heated to 250oC.  NH4NO3(s)  –> N2O(g)  + 2H2O(l) What volume of N2O gas is formed at 250oC and 1.0 atm when 5.00 grams of NH4NO3 is heated?  Type your numeric response in the box below. Do not include units.
