1.1(a) A sample of air occupies 1.0 L at 25 °C and 1.00 atm. What pressure is needed to compress itto 100 cm’ at this temperature?1.2(a) A perfect gas undergoes isothermal compression, which reduces itsvolume by 2.20 dm³. The final pressure and volume of the gas are 5.04 barand 4.65 dm', respectively. Calculate the original pressure of the gas in (a) bar,(b) atm.1.3(a) To what temperature must a 1.0 L sample of a perfect gas be cooled from 25 °C in order toreduce its volume to 100 cm³?1.4(a) A sample of 255 mg of neon occupies 3.00 dm at 122 K. Use the perfectgas law to calculate the pressure of the gas.1.7(a) In an attempt to determine an accurate value of the gas constant, R, astudent heated a container of volume 20.000 dm³ filled with 0.251 32 g ofhelium gas to 500°C and measured the pressure as 206.402 cm of water in amanometer at 25°C. Calculate the value of R from these data. (The density ofwater at 25°C is 0.997 07 g cm; the construction of a manometer is describedin Exercise 1.6a.)
