7. A hyperbaric chamber has a volume of 200. L. (a) How many moles of oxygen are needed to fill the chamber at room temperature (23°C) and 3.00 atm pressure? (b) How many grams of oxygen are needed? (Hint: Since moles have been asked, which equation has he moles listed in the equation. Use that to solve this problem. Also don't forget to use the equation 1 mole = Formula weight or Molecular weight to calculate the grams of 02).
