A typical barometric pressure in Denver, Colorado, is 615 mm Hg. What is this pressure in atmospheres and kilopascals? Please show steps

What is 32.0 psi of pressure in units of kilopascals (kPa)? Do not include the unit of measure in your answer.

A sample of gas consisting of 5.51 mol occupies a volume of 11.73 L. If another sample of the same gas (under identical conditions) consists of 14.76 mol, what volume in litres of gas are in the second sample? Provide your answer with TWO decimals.

dies if needed for this question. The stopcock connecting a 3.13 L bulb containing methane gas at a pressure of 3.64 atm, and a 3.04 L bulb containing hydrogen gas at a pressure of 1.29 atm, is opened and the gases are allowed to mix. Assuming that the temperature remains constant, the final pressure in the system is atm.

When 5.5 g sodium reacts with an excess of sulfuric acid at 32°C, what pressure of hydrogen gas will result in a 500.0 mL container?

If 4.352 mol of argon gas occupies a volume of 111.1 liters at a particular temperature and pressure, what volume does 25.33 moles of argon occupy under the same condition?

According to Dalton, the pressure exerted by a gas inside a container is proportional to the number of molecules of that gas.  If 4.00 x 1023 molecules of N2 and 2.00 x 1023 molecules of O2 are mixed in a container they exert a total pressure of 1686 torr.  What portion of that pressure (in torr units) is exerted by the N2?  Report answer to four significant figures in decimal notation. _____________________ torr,   What portion of that pressure (in torr units) is exerted by the O2?  Report answer to four significant figures in decimal notation. ____________________ torr
