You have come down with a nasty cold and would like to understand why the virus that infected you is making you feel so lousy. With a few basic facts, given here within the problem, you can show that each infected cell is now very full of virus particles, resulting in your current condition.

a. Given that a typical cell is about 10 um in diameter, calculate its volume in liters.
b. Find the concentration (in Molarity) of a single virus within that cell.
c. Find the concentration (in Molarity) of 100 virus particles within that cell.

a) The volume is 5.236x10⁻¹³L

b) The molarity of a single virus is 1.91x10¹² mol/L

c) The molarity for a 100 virus particles is 1.91x10¹⁴ mol/L

Explanation:

a) Given:

D = diameter of the cell = 10 μm

r = radius = 10/2 = 5 μm

The volume of the spherical cell is equal:

If 1 μm³ = 1x10⁻¹⁵L, then 523.6 μm³ = 5.236x10⁻¹³L

b) The molarity is:

For a single virus within the cell

c) For a 100 virus particles the molarity is:

i think so it’s will be b yes i believe its

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
