    You're going to use the PV = nRT formula. You'll add 273 to 25 to get the temperature in K and you'll plug in everything you know

    Into the formula. You also must change Liters into milliliters, so it will be 1200 ml. After putting everything into the formula you can solve it algebraically. The moles of gas would be about 540.19
