Chapter 8: Q. 8.84 (page 283)

In the fermentation of glucose (winemaking), 780mLofCO2gas was produced at 37掳Cand 1.00atm. What is the final volume, in liters, of the gas when measured at 22掳Cand 675mmHg. If the amount of gas does not change?(8.5)

Short Answer

Expert verified

The final volume is0.83L.

Step by step solution

01

Given Information

We need to find the final volume.

02

Simplify

Initial conditions as;

P1=1atmV1=780mL=0.78LT1=37掳C=(37-273)K=310K

Final conditions as:

P2=675mmHg=0.89atmT2=22掳C=(22+273)K=295K

Now, calculating the final volume V2:

PVT=ConstantV2=P1脳V1脳T2T1脳P2V2=1atm脳0.78L脳295K310K脳0.89atm=0.83L
