Question

At 971 mmHg, 3.3 moles of carbon dioxide have a volume of 34.13 L. What is the temperature of the sample, in °C?​

Answer 1

-112°C

Step-by-step explanation:

Given,

Pressure, P = 971 mmHg

moles of carbon dioxide = 3.3

Temperature, T = ?

Volume = 34.13 L

Pressure in atm =
`(971)/(760) = 1.278\ atm`

Now, using ideal gas equation

PV = n RT

1.278 x 34.13 =3.3 x 0.08206 x T

T = 161.07 K

Temperature in °C = 161.07-273 = -112°C

Temperature of sample is -112°C.
