If you inoculate 1*10^6 CFU/ml E.coli, assuming a population doubling time of 20 minutes. Calculate the total number of cells present in a 100 ml flask of LB broth after 6 hours.

If you are severely ill with fever due to Listeria, E. coli will not help you. Timely prescription of antibiotics can cure the infection. You can also have a bacterium...

The time taken by the bacteria to double in number during a period of certain time is the generation time. We will have 200 cells: bacteria will divide once during...

As bacteria divide every 20 minutes for 4 hours, the number of their division equals:4h / 20min = 240min / 20min = 12 divisionsThe number of bacteria after 12 divisions...

The nutrient broth is a transparent yellowish solution if any organisms are present. As a result, uninoculated and uncontaminated solutions are transparent and are not cloudy. The broth culture contains...

The generation time is the time interval required for the cells (or population) to divide.G (generation time) =t (time, in minutes)/n(number of generations)G = t/nt = time interval in minutes = 180...

Moles of Nitrogen = 0.3Moles of hydrogen = 0.4Volume = 10 LTemperature = 20 + 273 = 293 KPV = nRTPartial pressure of Nitrogen = 0.3×0.0821×208/10= 0.512atmPartial pressure of hydrogen=...

You can use the following law for solving this question: PfVf = P1V1 + P2V2 + P3V3 hellip; etc Pf is final pressure of the mixture Vf is Final volume...

The partial pressure of individual gas in the gas mixture can be expressed the following way: Pi = Ptotal *xi, Where Pi – is the partial pressure of individual gas...

Because it can be broken. Unlike round bottom flask, volumetric flask has local heating due to the tension in the glass.

Answer: Because all volumetric flasks are calibrated and graduated for liquids at standard temperature (usually 20 degrees Celcius). This temperature is indicated on the flask.
