Consider a 2000 liters large tank holding 1000 liters of pure water into which a brine water solution of salt begins to áow at a constant rate of 6 liters/min. the solution inside the tank is kept well stirred and is áowing out of the tank at a rate of 6 liters/min. if the concentration of salt in the brine entering the tank is 0: 1 kg/liter. (i) set up the initial value problem equation and solve the problem. (ii) determine when the concentration of salt in the tank will reach 0: 05 kg/liter.

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
