A student collects 629ml of oxygen at 0.500at, the student collected 0.0337 moles. At what temperature did the student collect t

VashaNatasha [74]

Answer:

114 K

Explanation:

Given data

Volume of oxygen (V): 629 mL = 0.629 L

Pressure of oxygen (P): 0.500 atm

Moles of oxygen (n): 0.0337 mol

Temperature (T): ?

We can calculate the temperature at which the student collected the oxygen using the ideal gas equation.

$P \times V = n \times R \times T\\T = \frac{P \times V}{n \times R} = \frac{0.500atm \times 0.629L}{0.0337mol \times 0.0821atm.L/mol.K} = 114 K$

The oxygen gas was collected at 114 K.
