How many particles can be stored in a 4.0 l container at room temperature (23c) and standard atmospheric pressure (101.3 kpa)

- There are particles in the container present at 23 degree C and 101.3 pKa.

Solution:- The given volume of the container is 4.0 L at 23 degree C and 101.3 kPa pressure.

We would calculate the moles using ideal gas law equation(PV = nRT) and then the moles are converted to particles on multiply the moles by Avogadro number.

Let's convert degree C to kelvin and pKa to atm.

T = 23 + 273 = 296 K

P = 101.3 pKa = 1 atm

R =

V = 4.0 L

n = ?

Let's plug in the values in the equation:

1(4.0) = n(0.0821)(296)

4.0 = n(24.3)

n = 0.165 mol

Let's multiply the moles by Avogadro number to get the number of particles:

= particles

So, from above calculations there would be particles in the container.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
