On a hot summer day, the density of air at atmospheric pressure at 34.5°C is 1.1242 kg/m3.

(a) What is the number of moles contained in 1.00 m3 of an ideal gas at this temperature and pressure? mol

(b) Avogadro's number of air molecules has a mass of 2.82 ✕ 10−2 kg. What is the mass of 1.00 m3 of air? (Assume air is an ideal gas.) kg

(c) Does the value calculated in part (b) agree with the stated density of air at this temperature? (Consider that it does if the values are within 10% of each other.) Yes or no?

Air (a diatomic ideal gas) at 26.5°C and atmospheric pressure is drawn into a bicycle pump (see figure below) that has a cylinder with an inner diameter of 2.50 cm and length 47.0 cm. The downstroke adiabatically compresses the air, which reaches a gauge pressure of 8.00 105 Pa before entering the tire. We wish to investigate the temperature increase of the pump. The pump is made of steel that is 1.80 mm thick. Assume 4.00 cm of the cylinder's...
