Agas occupying a volume of 673.0 ml at a pressure of 0.894 atm is allowed to expand at constant temperature until its pressure reaches 0.517 atm. what is its final volume?

1164 ml

Explanation:-

To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.  

The equation given by this law is:

where,

= initial pressure of gas= 0.894 atm

=  initial volume of gas = 673.0 ml

= final pressure of gas= 0.517 atm

= final volume of gas = ?

Putting values in above equation, we get:

Thus the final volume of the gas is 1164 ml.

i believe the answer is electric potential.

explanation:

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 =
