What's the volume of 0.2 mol of nitrogen at 20oC and 0.7 atm?

Whats The Volume Of 02 Mol Of Nitrogen At 20oC And 07 Atm class=

Sagot :

Explanation:

We have to determine the volume of 0.2 mol of nitrogen at 20 °C and 0.7 atm. The ideal gas law describes this situation.

P * V = n * R * T

Where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant and T is the temperature.

We already know these some of these values.

P = 0.7 atm

n = 0.2 mol

R = 0.082 atm * L/(mol*K)

T = 20 ° C = 293.15 K

We can use the ideal gas law to determine the volume of the sample.

P * V = n * R * T

V = n * R * T/P

V = 0.2 mol * 0.082 atm*L/(mol*K) * 293.15 K/(0.7 atm)

V = 6.86 L

Answer: The volume is 6.86 L.
