You fill a balloon with 0.525 moles of helium in a room that is 21 degrees celcius and the pressure is 1.005 atm. What is the volume of that balloon?
QUESTION 18 4.9 A balloon contains 17.33 L of gas at a pressure of 4.85 atm. What will the pressure be (in atm) if the volume is decreased to 6.27 L, with the temperature remaining constant?
A balloon containing 4.00 moles of N2 gas has a volume of 0.750 L at a pressure of 1.00 atm and a temperature of 27°C. What will the new volume of the balloon be, in liters, if the pressure is doubled to 2.00 atm, the temperature is increased to 127°C, and 1.50 moles of N2 is removed from the balloon? On an airliner, an inflated toy has a volume of 0.310 L at 25°C and 745 mmHg. During flight, the...
1)a If a sample of oxygen gas has a volume of 4.89 L at 20.0 °C and a pressure of 1.20 atm. If the temperature was increased to 56.0 °C then what would its resultant volume be (in L?) Assume the new pressure is 1.20 atm. b At STP, 297.0 mL of a certain gas has a mass of 0.366 g. What is a possible identity of this gas? Select one: a. O3 b. Cl2 c. C2H6 d. O2 e....

What was the temperature of the propane in the flask? ______°C b.)Butane,C4H10 , is an easily liquefied gaseous fuel. Calculate the density of butane gas at 0.791 atm and 24°C. Give the answer in grams per liter. Density = ______g/L c.) A 0.488-g sample of a colorless liquid was...
A gas-filled balloon with a volume of 2.10 L at 1.20 atm and 20°C is allowed to rise to the stratosphere (about 30 km above the surface of the Earth), where the temperature and pressure are −23°C and 3.00×10−3 atm, respectively. Calculate the final volume of the balloon.
A gas-filled balloon having a volume of 2.70 L at 1.20 atm and 26 ° C is allowed to rise to the stratosphere (about 30 km above the surface of the Earth), where the temperature and pressure are −41 ° C and 5.90 × 10−3 atm, respectively. Calculate the final volume of the balloon.
The volume of a sample of gas measured at 45.0°C and 1.20 atm pressure is 3.00 L. What must the final temperature be in order for the gas to have a final volume of 2.00 L at 1.20 atm pressure? a. 23.3°C b. –220°C c. 204°C d. 212°C e. - 61°C
A balloon vendor at a street fair is using a tank of helium to fill her balloons. The tank has a volume of 193.0 L and a pressure of 115.0 atm at 25.0 °C. After a while she notices that the valve has not been closed properly. The pressure had dropped to 105.0 atm. (The tank is still at 25.0 °C.) How many moles of gas has she lost? final volume= 211.38 L
