Moles out-of Energy and you may Volume: Avogadro’s Law
How many moles of gaseous boron trifluoride, BF3, are contained in a cuatro.34ten-L bulb at 788.0 K if the pressure is 1.dos20 atm? How many grams of BF3?
Iodine, I2, is a solid at room temperature but sublimes (converts from a solid into a gas) when warmed. What is the temperature in a 73.3-mL bulb that contains 0.292 g of I2 vapor at a pressure of 0.462 atm?
A leading altitude balloon is stuffed with step 1.41 10 cuatro L from hydrogen during the a temperature from 21 °C and you may a stress out-of 745 torr. What’s the amount of the fresh balloon at the a top off 20 km, where temperature is –forty-eight °C together with pressure was 63.step one torr?
A cylinder of medical oxygen has a volume of 35.4 L, and contains O2 at a pressure of 151 atm and a temperature of 25 °C. What volume of O2 does this correspond to at normal body conditions, that is, 1 atm and 37 °C?
A large diving container ((Figure)) with an amount of 18 L was rated to own a stress out of 220 pub. The fresh container are occupied in the 20 °C features adequate heavens to offer 1860 L off air to a diver within a pressure from 2.37 atm (a level of forty five legs). Are brand new container filled in order to ability at the 20 °C?
A 20.0-L cylinder containing kg of butane, C4H10, was opened to the atmosphere. Calculate the mass of the gas remaining in the cylinder if it happn were opened and the gas escaped until the pressure in the cylinder was equal to the atmospheric pressure, 0.983 atm, and a temperature of 27 °C.
While resting, the average 70-kg human male consumes 14 L of pure O2 per hour at 25 °C and 100 kPa. How many moles of O2 are consumed by a 70 kg man while resting for 1.0 h?
A liter of methane gas, CH4, at STP contains more atoms of hydrogen than does a liter of pure hydrogen gas, H2, at STP. Using Avogadro’s law as a starting point, explain why.
The effect of chlorofluorocarbons (such as CCl2F2) on the depletion of the ozone layer is well known. The use of substitutes, such as CH3CH2F(g), for the chlorofluorocarbons, has largely corrected the problem. Calculate the volume occupied by 10.0 g of each of these compounds at STP:
Since step 1 grams of one’s radioactive function radium decays over 1 season, they provides step one.16 ten 18 leader particles (helium nuclei). For every alpha particle will get an atom of helium energy. What’s the tension within the pascal of the helium gas delivered whether it occupies a level of 125 mL during the a fever away from 25 °C?
A balloon which have a quantity of L at the 21 °C and you may 0.981 automatic teller machine arrives and simply rarely clears the top of Mount Crumpet when you look at the British Columbia. If the finally level of the latest balloon was L on good temperatures of 5.twenty four °C, what’s the pressure knowledgeable of the balloon since it clears Install Crumpet?
In case your heat away from a predetermined quantity of a gasoline try twofold in the lingering frequency, what happens towards the pressure?
If the quantity of a fixed number of a gasoline is actually tripled on lingering temperatures, what goes on into tension?

Services (a) The fresh new can also be consists of some isobutane gasoline within a reliable frequency, anytime the temperature is enhanced from the temperatures, the pressure increase proportionately. High temperature may lead to ruthless, causing the normally to-burst. (As well as, isobutane try flammable, so incineration can cause the brand new is so you can burst.)
Look at the Discovering What is the level of an example away from ethane during the 467 K and you will step 1.step 1 automatic teller machine if this uses up 405 mL during the 298 K and you will 1.step one automatic teller machine?
Look at your Understanding Calculate pressure in club out-of 2520 moles away from hydrogen fuel kept at twenty-seven °C regarding the 180-L stores tank from a modern-day hydrogen-driven auto.
Practical Requirements off Temperatures and you can Tension
The quantity out of a car sky wallet is actually 66.8 L when expensive from the twenty-five °C with 77.8 g from nitrogen gasoline. That was the stress regarding purse inside kPa?
