A mixture of gases collected over water at 14oC has a total pressure of 1.198 atm and occupies 72 mL. How many grams of water escaped into the vapor phase?
Solutions
Expert Solution
The total pressure of gases over water at140 C, P = 1.198 atm
at 140 C the vapour pressure ofwater = 0.016atm
Total volume = 72.mL
= 0.072 L
Temperature = (14 +273 ) K
= 287 K
Ideal gas equation PV = nRT
so number of water moles , n = PV / RT
= ( 0.016 atm * 0.072L) / (0.08206 L.atm /mol.K*287K)
= 4.89 x 10-5 mol
molar mass of water = 18 g / mol
Therefore mass of water present in vapor state ,m = 18g /mol x 4.89 x 10-5 mol
= 8.80 x 10-4 g
8.80 x 10-4 g of water is escaps into vapor phase

Dalton's law states that the total pressure, Ptotal, of a
mixture of gases in a container equals the sum of the pressures of
each individual gas: Ptotal=P1+P2+P3+… The partial pressure of the
first component, P1, is equal to the mole fraction of this
component, X1, times the total pressure of the mixture:
P1=X1×Ptotal The mole fraction, X, represents the concentration of
the component in the gas mixture, so X1=moles of component 1total

A mixture of CH4 (g) and C2H6 (g) has a total pressure
of 0.53 atm. Just enough O2 was added to the mixture to bring about
it's complete combustion to CO2 (g) and H2O (g). The total pressure
of the two product gases is found to be 2.2 atm. Assuming constant
volume and temperature, find the mole fraction of CH4 in the
original mixture.

1.The total pressure of a mixture of O2(g) and H2(g) is 1.95
atm. The mixture is ignited and the resulting water is removed. The
remaining mixture is pure H2(g) and exerts a pressure of 0.210atm
when measured at the same temperature and volume as the original
mixture. What were the mole fractions of O2(g) and H2(g) in the
original mixture?

1.) The total pressure (PT) os a sample of a gas
collected over water at 13.0oC is 0.588 atm. Determine
the partial pressure (Pi) of the gas.
2.) Rearrange the ideal gas equation to solve for density (g/v).
Hint: you will need to make a substitution for moles "n"
3.) Use your quation from (z) and the result from (l) to
calculate the molecular weight of a gas if 303 ml of the gas,
collected at 28oC, weighed 0.347g.
