How many moles of oxygen (O2) are present in 33. 6 L of the gas at 1 atm and 0°C? 1. 5 2 22. 4 32.
oee [108]

The number of moles of oxygen in the gas is 1.5 L.

The correct option is (A).

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

\bold{\dfrac{33.6}{22.4 } =1.5\; mole}

Thus, option A is correct. 1.5 L.
