To determine the number of moles of oxygen gas ( ) in 50.0 L, we can use the ideal gas law under standard temperature and pressure (STP) conditions. At STP, 1 mole of any ideal gas occupies 22.4 liters.Given:- Volume of = 50.0 L- Molar volume at STP = 22.4 L/molWe can calculate the number of moles using the formula: Substituting the given values: Therefore, the correct answer is 2.23 moles.
