ligh-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical ubstances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa 50,000,000 Pa). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of .26×10® Pa , what is its running pressure in torr? Express the pressure numerically in tor.

After 1.60 mol of NH3 gas is placed in a 1600-cm3 box at 25 Celcius, the box is heated to 500 K. At this temperature, the ammonia is partially decomposed to N2 and H2 and a pressure measurement gives 4.85 MPa. Find the number of moles of each component present at 500 K.
An experiment is conducted in which a quantity of H2(g) is chemically generated in a closed headspace of volume V1 at absolute temperature T1, thereby raising the total pressure from Pa (the initial air pressure) to Pf (the total final pressure of H2(g) + air).Compose an algebraic expression for the volume (V2) that this sample of H2(g) would occupy if it were isolated (pure -- i.e. no air) at absolute temperature T2 and partial pressure P2.Note that your expression may contain no other variables than those given above, namely: V1, T1, T2, Pa, Pf, and P2.

Insects do not have lungs as we do, nor do they breathe through their mouths. Instead, they have a system of tiny tubes, called tracheae, through which oxygen diffuses into their bodies. The tracheae begin at the surface of the insect's body and penetrate into the interior. Suppose that a tracheae is 1.34 mm long with a cross-sectional area of 2.46 x 10-9m2. The concentration of oxygen in the air outside the insect is 0.794 kg/m3, and the diffusion constant is 1.26 x 10-5 m2/s. If the mass per second of oxygen is diffusing through a trachea is 1.66 x 10-12 kg/s, then find the oxygen concentration at the interior end of the tube.
