A student experimentally determines the gas law constant, R, by reacting a small piece of
magnesium with excess hydrochloric acid and then collecting the hydrogen gas over water
in a eudiometer. Based on experimentally collected data, the student calculates R to equal
L'atm
0.0832
mol·K
L'atm
Ideal gas law constant from literature: 0.08206
mol·K
(a) Determine the percent error for the student's R-value.
Percent error =|1.389
(b) For the statements below, identify the possible source(s) of error for this student's trial.
The student uses the barometric pressure for the lab to calculate R.
The student does not equilibrate the water levels within the eudiometer and the
beaker at the end of the reaction. The water level in the eudiometer is 1-inch
above the water level in the beaker.
The student does not clean the zinc metal with sand paper.
The student notices a large air bubble in the eudiometer after collecting the
hydrogen gas, but does not dislodge it.
A 5.50-mole sample of NH3 gas is kept in a 1.85-L container at 309 K. If the van der Waals equation is assumed to give the correct answer for the pressure of the gas, calculate the percent error made in using the ideal-gas equation to calculate the pressure. (Use a = 4.17 atm·L2·mol−2 and b = 0.0371 L·mol−1 for the van der Waals equation.)
Sulfur dioxide reacts with oxygen in the presence of plati-
num to give sulfur trioxide:
2 SO2(g) + O2(g) → 2 SO3(g)
Suppose that at one stage in the reaction, 26.0 mol SO2,
83.0 mol O2, and 17.0 mol SO3 are present in the reaction
vessel at a total pressure of 0.950 atm. Calculate the mole
fraction of SO3 and its partial pressure.
