Answer:

0.0559 mol

Explanation:

Step 1: Given and required data

  • Volume of air (V): 1.35 L
  • Pressure of air (P): 750 torr
  • Temperature (T): 17.0 °C
  • Ideal gas constant (R): 0.0821 atm.L/mol.K

Step 2: Convert "P" to atm

We will use the conversion factor 1 atm = 760 torr.

750 torr × 1 atm/760 torr = 0.987 atm

Step 3: Convert "T" to Kelvin

We will use the following expression.

K = °C + 273.15

K = 17.0 °C + 273.15 = 290.2 K

Step 4: Calculate the number of moles of air

If we assume air behaves as an ideal gas, we can calculate the moles (n) of air using the ideal gas equation.

P × V = n × R × T

n = P × V/R × T

n = 0.987 atm × 1.35 L/(0.0821 atm.L/mol.K) × 290.2 K = 0.0559 mol

Brut [27]
I think the best answer from the choices listed above is option B. The best graduated cylinder for this case is the glass cylinder. A metal cylinder is not possible because you cannot measure really since metals are not transparent. A plastic cylinder cannot also be used since the substance should be heated for the experiment.
