3. A large balloon is in a room that is 754 mm Hg and 23 °C. ||| a. If the balloon contains 2.00 L of helium, how many moles of helium are in the balloon?" b. If I untie the knot and release some gas until only 0.25 g of helium remains and then retie the knot, what is the new volume of the balloon? (Assume the temperature and pressure from the beginning of the problem did not change.)
