1) Dextran is a polymeric carbohydrate produced by certain bacteria. It is used as a blood plasma substitute. An aqueous solution contains 0.582g of the Dextran in 106 mL of solution. It has an osmotic pressure of 1.47 mm of HG.
b) what is the molarity of that Dextran solution. Hint use the osmotic pressure equation T=298k, R = 0.0821L ATM / mol k.
c) how many moles of dextran are present in the 106 mL solution. Use the molarity equation.
d) what is the molar mass of the solute. MM= mass/mole.

A certain drug can be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux. The manufacturer of the drug claims that more than 93​% of patients taking the drug are healed within 8 weeks. In clinical​ trials, 216 of 231 patients suffering from acid reflux disease were healed after 8 weeks. Test the​ manufacturer's claim at the alpha equals 0.05 level of significance.

1. A researcher studying the lifespan of a certain species of bacteria. A preliminary sample of 35 bacteria reveals a sample mean of ¯ x = 64 x ¯ = 64 hours with a standard deviation of s = 5.6 s = 5.6 hours. He would like to estimate the mean lifespan for this species of bacteria to within a margin of error of 0.5 hours at a 98% level of confidence. What sample size should you gather to achieve...

1) In a batch culture, formic acid (HCOOH) is produced using bacteria. For each mole of glucose (C6H12O6) utilized by the bacteria, 2.40 moles of cells (CH1.80O0.51N0.26), 1.70 moles of formic acid, 1.90 moles of gaseous CO2, and some H2O are formed. Oxygen (O2) and ammonia (NH3) were consumed. Glucose, ammonia and 18,350 kg of water were fed to the reactor and inoculated with the bacteria. Air is pumped into the reactor and during the entire process 6000 kg of...
