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.
The universal gas constant, R, is defined as the following:
kg · m²
s2 · K• mol
R = 8.314
What would be its value in the following unit?
lb· cm?
day2 · K• mol
1. Where did the R constant in PV=nRT come from, and why must we convert everything to the units of the R constant?
2. Why does the density of water change with its temperature?
3. If all of the gas was not vaporized before taking the mass (some stayed in liquid form), how would that affect the final molar mass calculation?
4. If a sample of ethanol (C2H6O) was determined to have a pressure of 2 atm at a temperature of 25°C, what is its density (in g/L)?
