what does =102 mean?
At what temperature (in degrees C ) does acetone have Pvap= 102mmHg?
To determine the temperature at which acetone has a vapor pressure of 102 mmHg, we can refer to a vapor pressure chart or use the Antoine equation. The Antoine equation can be used to estimate the vapor pressure of a substance at different temperatures.
The Antoine equation for acetone is:
log(P) = A - (B / (T + C))
Where:
P is the vapor pressure in mmHg
T is the temperature in degrees Celsius
The constants A, B, and C for acetone are:
A = 14.314
B = 2756.22
C = -47.72
To find the temperature at which acetone has a vapor pressure of 102 mmHg, we can rearrange the Antoine equation and solve for T:
T = (B / (A - log(P))) - C
Substituting the given vapor pressure (P = 102 mmHg) into the equation, we have:
T = (2756.22 / (14.314 - log(102))) - (-47.72)
Using a scientific calculator, we can calculate the value of log(102) = 2.0086.
T = (2756.22 / (14.314 - 2.0086)) - (-47.72)
T = (2756.22 / 12.3054) + 47.72
T ≈ 224.13 °C
Therefore, acetone has a vapor pressure of 102 mmHg at approximately 224.13 °C
