The volumetric flow rate of aniline is 1500 cm/min. what is the mass flow rate in g/sec? what is the molar flow rate in kmol/min? (2) the volumetric flow rate of a 4m ammonium nitrate aqueous solution is 450 m/hr. the specific gravity of the solution is 1.54. what is the mass fraction of ammonium nitrate? 2. (5pt) (1) you have a combination of gases exiting a flue stack. the composition of the gas is 5 wt% co, 65 wt% co2, 20 wt% hạ0, and 10 wt% so2. what is the average molecular weight of the gas? if the percentages were the same, but mol% instead, what is the average molecular weight of the gas? (2) the marianas trench is the deepest place on the planet, with a depth of 6.831 miles. what is the pressure at the bottom of the trench, if you assume that the density of water is 1000 kg/m²and does not change, gravity is 9.81 m/s", and the pressure at the surface is 1 atm?
