675 C 1200)- 2 (b) - A balloon with a volume of 220 mL is filled with 2.0 moles of Helium. To what yolume will the balloon expand if an additional 3.0 moles of Neon are added?.
A weather balloon with a volume of 44L is filled with 2.0 mol of helium. What is the final volume, in liters if 3.0 mol of helium are added, to give a total of 5.0 mol of helium, if the pressure and temperature do not change?
1. A helium-filled birthday balloon has a volume of 223 mL at a temperature of 24°C (room temperature). The balloon is placed in a car overnight during the winter where the temperature drops to -13°C. What is the balloon’s volume, in milliliters, when it is removed from the car in the morning (assuming no helium has escaped)?
Adding helium to a balloon increased its volume from 427.7 mL to 3.350 L. If the final number of moles of helium in the balloon is 22.5 mol, what was the initial number of moles of helium in the balloon? Assume the balloon contained only helium initially. _______________________mol
A balloon is filled to a volume of 7.45 x 102 mL at a temperature of 15.0°C. The balloon is then cooled at constant pressure to a temperature of 1.32 x 102 K. What is the final volume of the balloon? Volume = mL
Question 23 6 pts A different balloon filled with helium, originally had a volume of 7.50 liters, at 18.0°C. As the day became warmer the new temperature was 38.0°C. What would the new volume of the balloon be, assuming there is no change in pressure or moles of gas? (Show all your work!!!!)

A balloon filled with 35.6 moles of helium has a volume of 856 L at 0.0°C and 1.00 atm pressure. The temperature of the balloon is increased to 43.0°C as it expands to a volume of 967 L, the pressure remaining constant. Calculate q, w, and ΔE for the helium in the balloon. (Given, the molar heat capacity for helium gas is 20.8 J/°C · mol, and 1 L·atm = 101.3 J) (Show your work)
A 0.300 kg balloon is filled with helium until the volume of the balloon is 1.50m3. The density of the contained helium is 0.178 kg/m3, and the density of the surrounding air is 1.29 kg/m3. What downward force must be applied to the balloon to prevent it from rising?
A helium-filled balloon has a volume of 2.9 L at 23◦C. The volume of the balloon decreases to 2.5 L after it is placed outside on a cold day. What is the outside temperature in ◦C?
A helium-filled balloon has a volume of 2.9 L at 23◦C. The volume of the balloon decreases to 2.5 L after it is placed outside on a cold day. What is the outside temperature in ◦C? Answer in units of ◦C.
