Agas stream flows at a rate of 14 m3/s at 322 k and 172 kpa. it consists of a mixure of 52 mole % ammonia in air. the gas enters through the bottom of a packed-bed gas absorber, where it flows countercurrent to a stream of pure liquid water that absorb 90% of all of the ammonia, and virtually no air. the absorber vessel is cylindrical with an internal diameter of 2.5 m. (a) neglecting the evaporation of water, calculate the ammonia mol fraction in the gas leaving the absorber. (b) calculate the outlet gas mass velocity (defined as mass flow rate per unit empt

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
