How do I calculate the number of moles of oxygen in 1.00 L at 25 degrees Celsius and 1.00 atm, assuming the gas behaves ideally?
The Ideal Gas Law Equation is PV=nRT so you do
1*1=n*25 Disregard the R for now has no importance in ideal gas laws
So we have 1=n*25 and you want to get n by itself so you do inverse operations which means you divide both sides by 25
1/25=n*25/25←cancels out and the equation is now 1/25=n and you get the answer which is 0.04 moles
