A balloon contains 75.0 grams of carbon tetrafluoride gas with a volume of 159 dL at a temperature of 375 K. What is the pressure of the gas? (Show calculations, and the units.)
Homework Answers
mass of CF4 = 75.0 g
moles of CF4 = 75.0 / 88 = 0.852 mol
volume = 159 dL = 15.9 L
temperature = 375 K
P V = n R T
P x 15.9 = 0.852 x 0.0821 x 375
P = 1.65 atm
pressure = 1.65 atm

Consider a balloon that has a volume V. It contains n moles of gas, it has an internal pressure of P, and its temperature is T. If the balloon is heated to a temperature of 15.5T while it is placed under a high pressure of 15.5P, how does the volume of the balloon change? It doubles. It stays the same. It increases greatly. It decreases slightly.

A balloon contains 1 moles of helium gas at normal atmospheric pressure (Patm = 1.01 105 Pa) and room temperature (293 K). The volume of the balloon is 0.024 m^3. (b) The weather becomes very stormy (a hurricane is approaching), and the volume of the balloon increases by 10.9%. What is the new pressure? ______kPa? (the answer is not 9.26x10^2)
A sample of an ideal gas at 1.00 atm and a volume of 1.76 L was placed in a weighted balloon and dropped into the ocean.
Question 4 of 21 A sample of an ideal gas at 1.00 atm and a volume of 1.76 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 75.0 atm, what was the volume of the sample? Assume that the temperature was held constant.Questions of 21 A hot air balloon is filled with 1.31 x 10 L of an ideal...
