A sample of nitrogen dioxide gas occupies 625 cm3 at 70.0 °C and 15.0 psi.What is the final Celsius temperature if the volume is 545 cm3 at 15.0 psi?

Question

Quizplus · Accepted Answer

Using the combined gas law:

(P1V1/T1) = (P2V2/T2)

We can rearrange the formula to solve for the final temperature:

T2 = (P2V2T1)/(P1V1)

Plugging in the given values:

T2 = (15.0 psi x 545 cm3 x 343 K)/(15.0 psi x 625 cm3)
T2 = 26 K

Converting to Celsius:

T2 = 26 K - 273.15
T2 = 26 °C

Therefore, the final Celsius temperature is 26 °C.
