The number of moles of oxygen in the gas is 1.5 L.
The correct option is (A).
The mole is the International System of Units' foundation unit of material quantity.
Given,
The volume of gas is 33.6 L
Pressure is 1 atm.
Temperature is 0°C
Molar gas volume is 22.4 L
There is no temperature and pressure is 1 atm.
By formula of moles, volume is divided by molar mass
[tex]\bold{\dfrac{33.6}{22.4 } =1.5\; mole}[/tex]
Thus, option A is correct. 1.5 L.
