Problem- The concentration of a biomolecule inside a rod-shaped prokaryotic cell is 0.0053 M. Calculate the number of molecules inside the cell, which is 2.9um long and 1.4um in diameter.
You must show your work in an efficient manner so I can understand it in clearly
Describe and explain the possible effect on your results of the following experimental errors or variations. In each case specify the component(s) whose percentage(s) would be too high or too low.
With acid-catalyzed condensation of a molecule with two aldehyde groups that is suitable for forming 5- or 6-membered rings, are both carbonyls protonated right away at the same time
To better understand why, scientists synthesized artificial protein mimics that were linked by ester bonds instead of the amide functionality ( the R-group side chains all remained the same). They found that these mimics did not form highly organi..
A 88.0-L sample of dry air is cooled from 135.9°C to 45.4°C while the pressure is maintained at 2.85 atm. What is the final volume in L. (Do not type the units.) the answer is 68.5 but using the charles law doesnt work. can someone explain it to m..
871 test of an unknown acid requires 32.9 mL of a .187 Mbarium hydroxide solution for neutralization. Assuming the acid is diprotic, Compute the molar mass of the acid.
Determine how much heat is released when 14.8 kilo grams of Ethylene forms and The Hydrogen gas is collected over H2O(water) at a temperature of twenty five degree celsius and a total pressure =762 mmHg. (The ideal gas law constant R = 0.0821L*atm/..
Estimate the density of Rb if it crystallizes in a body-centered cubic unit cell and has an atomic radius of 247.5 pm.
The solubility of 1-hexanol in water is 0.60 g per 100 g of water at 25 degrees C. What is the maximum amount of 1-hexanol that will dissolve in 7.9 g of water at 25 degrees C
Propose ways with appropriate equations that would enable you to measure the D H ° f values of Ag 2 O( s ) and CaCl 2 ( s ) from their elements. No calculations are necessary.
Xenon gas is released during a certain chemical reaction and pushes back the atmosphere with a change in volume of the vessel (it has a movable piston) from 2 to 20 Liters. Calculate the work done by this release of gas.
Calculate the molarity and mole fraction of acetone in a 1.25 m solution of acetone (CH3COCH3) in ethanol (C2H5OH). (Density of acetone = 0.788 g/cm3; density of ethanol = 0.789 g/cm3.) Assume that the volumes of acetone and ethanol add. molarity ..
