Gram molecular volume of oxygen at STP is (KCET 2007)

A.3200 cm3

B.5600 cm3

C.22400 cm3✓ Correct

D.11200 cm3

Explanation

At standard temperature-pressure conditions (STP), the gram molecular volume of any gas is around 3 22400cm . STP Conditions: Temperature = 273.15 K Pressure = 1 atm Gram molecular volume is the volume of one mole of gas. Therefore, the volume of one mole of oxygen is 3 22400cm or 22. 4 L.
