34.4 gallon of toluene, 85.4 lbm of ethyl acetate, and 3.26 ft cubic of ethanol is poured into a tank. Find the mass fraction of each component.

Consider the following ternary diagram. The diagram is drawn to scale. The compositions are in mass  percentages. Mixtures R and Q were mixed in a 3:1 mass ratio. The resulting mixture is then fed to a distillation column, which separates all the C as the distillate. Determine the mass and composition of the bottoms if 25 kg of R was used.

A bucket contains 10 kg of water and 10 kg of NaOH. The respective mass fraction of water and the mole fraction of NaOH are

A sample of medium-grade bituminous coal analysis is as follows: соmponent percent 2 1 6 Ash Water 11 3 The residuum is C and H in the mole ratio H/C = 9. Calculate the composition of the coal with the ash and the moisture omitted.

3.59. WP An open-end mercury manometer is connected to a low-pressure pipeline that supplies a gas to a laboratory. Because paint was spilled on the arm connected to the line during a laboratory renovation, it is impossible to see the level of the manometer fluid in this arm. During a period when the gas supply is connected to the line but there is no gas flow, a Bourdon gauge connected to the line downstream from the manometer gives a reading of 7.5 psig. The level of mercury in the open arm is 900 mm above the lowest part of the manometer. BOURDON GAUGE PIPEN Paint h = 900 mm a. When the gas is not flowing, the pressure is the same everywhere in the pipe. How high above the bottom of the manometer would the mercury be in the arm connected to the pipe? b. When gas is flowing, the mercury level in the visible arm drops by 25 mm. What is the gas pressure (psig) at this moment?

Convert 23lbf ∙ ft/min2 to its equivalent in kg ∙ cm/s2. NOTE: it is lbf not lb.

(a) using data in Appendix A,calculate the number of iron atoms in one ton(2000 pounds)of iron. (b) Using data in Appendix A,calculate the volume in cubic centimeters occupied by one mole of boron.

A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods.

Calculate the number of moles and the mass of the solute in 10.5 L of 3.716 M (NH4)2SO4, a liquid fertilizer.
