How many moles of gaseous boron trifluoride, BF_{step step three}, are contained in a cuatro.3410-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 top height balloon is full of 1.41 ten cuatro L of hydrogen from the a temperature out of 21 °C and you may a stress away from 745 torr. What’s the number of the fresh new balloon at a level away from 20 kilometer, the spot where the temperature is –forty-eight °C while the stress is 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 scuba container ((Figure)) having a level of 18 L was ranked for a pressure out-of 220 pub. This new tank are filled in the 20 °C and it has adequate sky to offer 1860 L anastasiadate kvízy away from sky to a scuba diver within a stress away from dos.37 automatic teller machine (a depth away from forty-five legs). Are the brand new tank occupied to strength within 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 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:

As 1 grams of the radioactive ability radium decays over step 1 seasons, they provides step one.16 ten 18 alpha dust (helium nuclei). For every leader particle gets a keen atom out of helium energy. What is the stress in the pascal of your own helium gas lead if this occupies an amount of 125 mL in the a temperature of 25 °C?

A balloon with a volume of L within 21 °C and you may 0.981 automatic teller machine happens and just rarely clears the top Install Crumpet inside the Uk Columbia. If for example the final number of new balloon are L in the a beneficial temperature of five.twenty four °C, what’s the pressure educated because of the balloon since it clears Attach Crumpet?

Whether your heat away from a fixed number of a fuel are doubled on constant regularity, what are the results to your stress?

Whether your volume of a predetermined amount of a petrol is tripled at constant temperatures, what will happen with the stress?

Licenses

Services (a) The latest normally include an amount of isobutane fuel on a constant regularity, so if the warmth try improved by heating, the stress will increase proportionately. High temperature may lead to high-pressure, causing the is to burst. (Plus, isobutane try flammable, therefore incineration trigger the new can be in order to burst.)

Look at your Discovering What is the volume of a sample regarding ethane in the 467 K and you will step one.step one atm if it occupies 405 mL at 298 K and you may step one.step one atm?

Check your Reading Calculate pressure when you look at the bar from 2520 moles from hydrogen gas held at twenty seven °C throughout the 180-L stores container regarding a modern-day hydrogen-powered vehicle.

Standard Conditions away from Temperatures and you can Tension

The amount out-of an automobile sky wallet was 66.8 L when excessive at the twenty five °C having 77.8 grams regarding nitrogen energy. What was the pressure on bag for the kPa?
