A sample of ammonia (NH3), a colorless gas with a pungent odor, occupies a volume of 8.00 L at a pressure of 655 mm Hg and a temperature of 25°C. What volume, in liters, will this NH3 sample occupy at the same temperature if the pressure is increased to 725 mm Hg? Volume

A hot air balloon is filled with 1.39 × 10° L of an ideal gas on a cool morning (11 °C). The air is heated to 113 °C. What is the volume of the air in the balloon after it is heated? Assume that none of the gas escapes from the balloon. volume: L

A sample of polyatomic gas weighs 6.94 g and at a temperature 30.0 C it has a volume of 2.49 L and a pressure of 361 torr.   What is the molecular weight of the gas? (hint: remember that PV=nRTPV=nRT) The molecular structure of the gas in the above problem has a total of 7 atoms and contains only sulfur and fluorine atoms. Based on its molecular weight you calculated above, which of the following empirical formulas is most likely to be correct for the gas? SF6 S2F5 S3F4 S4F3 S5F2 S6F None of these formulas are correct

Your laboratory professor opens a bottle of H₂S and a bottle of ether, C4H10O at the same time. Both are gases at the same temperature and pressure. Which smelly gas should you detect first? Molar Masses: C = 12.01, H = 1.01, S = 32.07, O = 16.00. I OH₂S OC₂H₁00 Oneither, since they are more dense than air. Oboth at the same time

If the temperature of a 15.0 mL sample of N₂ gas is increased from 25.0 °C to 75.0 °C as its pressure remains constant, what will be its new volume in milliliters?

What is the final temperature of a gas (in °C) that starts at a pressure of (4.51x10^2) mm Hg, a volume of (8.400x10^0) L, and a temperature of (3.270x10^1)°C and is changed to a pressure of (7.3000x10^2) mm Hg and a volume of (6.9000x10^0) L?
