Question

80 liters of oxygen is collected over water at 50.0 degrees Celsius. The atmospheric pressure during the collection was 96.00 kpa. What is the partial pressure of the oxygen?

Answer 1

Answer:

The value of partial pressure of oxygen $P_{O_{2} }$ = 83.66 K pa

Explanation:

Volume of oxygen = 80 liters

Temperature = 50°c

The total pressure = 96 K pa

The partial pressure of water at 50°c is calculated from the tables.

$P_{H_{2}O }$ = 12.344 K pa

The total pressure is given by

$P_{total} =$ $P_{H_{2}O } + P_{O_{2} }$

Put all the values in the above equation we get

96 = 12.344 + $P_{O_{2} }$

$P_{O_{2} } =$ 96 - 12.344

$P_{O_{2} }$ = 83.66 K pa

This is the value of partial pressure of oxygen.
