An open-end mercury manometer is to be used to measure the pressure in an apparatus containing a vapor that reacts with mercury. A 10-cm layer of silicon oil (SG = 0:92) is placed on top of the mercury in the arm attached to the apparatus. Atmospheric pressure is 765 mm Hg.(a) If the level of mercury in the open end is 365 mm below the mercury level in the other arm, what is the pressure (mm Hg) in the apparatus?(b) When the instrumentation specialist was deciding on a liquid to put in the manometer, she listed several properties the fluid should have and eventually selected silicon oil. What might the listed properties have been?
Tooling for a vacuum deposition system is cleaned and reassembled. Unfortunately, a drop of water 0.125 cm3 in volume is left in the bottom of a screw hole. Due to the obstructed path to the pump, a negligible amount of water escapes during the early stages of pumpdown, and the drop becomes a virtual leak at a chamber pressure of 4.3E-06 torr. Find the volume of gas formed by the water at this pressure (assume it stays at room temperature). The density of water is 1g cm-3 and the molecular weight 18 g mole-1. (First, determine the number of moles in the drop of water, and use the ideal gas law to determine the volume)(b) To make this result clearer, what is the added time (in hours) to pump out this chamber due to this droplet if the pump, at that pressure, has a rate of 1480 L/s?
An oxygen cylinder used as a standby source of oxygen contains 7.0 ft^3 of O2 at 587 degR and 212.0 psig. What will be the volume (ft^3) of this O2 in a dry-gas holder at 650degR and 5.00 in. H2O above atmospheric (gauge)? The barometer reads 29.92 in. Hg. Conversion factors: 1 in. H2O = 0.0734824 in. Hg; Atmospheric pressure = 29.92 in. Hg = 1 std atm = 14.7 psia

6. A nitrogen gas (MW = 28) occupies a volume of 5ft3 at 2550 lb/ft2 abs and 755oR. What are its specific volume and specific weight? (3 DECIMAL IN FINAL ANSWER PLS!!)
Here in this PV=nRT problem, I solve for the temperature in C. 800 mm Hg / 760 mm Hg = 1.052631579atm. Chlorine gas is cl2, 100g/70.9g=1.410437236. After algebra, I get 227.211655. Is my answer off because I needed to round somewhere?
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. A) V2 = Now, suppose that the above experiment generated n mol of H2(g), that T2 = 0 °C and that P2 = 1 atm. Give the simple algebraic expression, in terms of V2 and n, which equates to the molar volume of H2(g) at STP. B) VM =
