- PV = nRT. The pressure is 0.9912atm. V = 50.5 mL. T = 21.5°C and n = 0.00200mol. Calculate R from this data in Latm/molK.A drug is infused continuously intravenously (IV) for treatment of a particular disease. The volume of the body fluid V = 16 liters. The drug is excreted (removed) through the kidneys at rate ke , proportional to the concentration of the drug in the body fluids. The drug is ineffective and not used by the body if its concentration is below Cmin and becomes poisonous if the concentration goes over Cmax . It is metabolized at a rate km as the concentration is >=Cmin. Let the parameter values Cmin= 4 mg/l, Cmax =40 mg/l, ke = 0.2/hr and km = 0.3/hr.a. How much is the maximum possible rate of infusion of the drug?b. How long the drug would continue to be effective if the infusion has been stopped as the concentration reached at the maximum level?Provide the remaining data missing

What is the could be the MW of the volatile sample?Show solution : if 12m³ of nitrogen at constant temp of 30°c and 12kpa abs is permitted to expand to 30m³, what is the resulting pressure? Ans. 50 kpahttps://m.youtube.com/watch?v=vM1SP346XBc&list=PLeJOSNLNZfHubfLdq0kOayASeUllMOGn4&index=4 I watched this the lecture video over and over and I am allowed to work with someone but I am having trouble with part B and I provided the YouTube link of the data or video attached to this lab
- Basis: https://youtu.be/Y4NMpO1xI8UA monolayer of CO molecules is adsorbed on the surface of 1.00 g of an Fe/AI2O3 catalyst at 77 K, the boiling point of liquid nitrogen. Upon warming, the carbon monoxide occupies 4.25 cm3 at O oC and 1.00 bar. What is the surface area of the catalyst?One of the highest concentrations of peroxyacyl nitrates has been found in the Los Angeles (LA) basin at 30 ppbppb, reaching its peak at mid-afternoon. Most of the pollution in the LA basin is created in an area of only 3000 km2km2 and the pollution depth below the inversion layer is normally about 500 mm. This concentration was therefore found in 1500 km3km3 of air above Los Angeles. Peroxyacyl nitrates contain two relatively weak bonds that can be broken by low-energy photons. The weakest is the N−ON−O bond in the nitrate functional group of the molecule with a standard bond-dissociation energy of 201 kJ mol−1. What is the longest wavelength of a photon, in nanometres, that has enough energy to cause the photodissociation of the weakest bond. Assume all energy of the photon is efficiently used for the photodissociation.
