Determine the percent error in the vapor volume from the real
value (experimental data) for n-butane at 15 bar, 125oC
using the follow equations of state:
A 56.0%/44.0% by volume propane/n-butane mixture is cooled from
375°C to 105°C. FInd the change in ethalpy of this mixture by
following the steps below. Assume ideal behavior. a) a) What is the
average molar mass of the mixture?
b) What is the change in specific enthalpy of pure propane from
375°C to 105°C?
c) What is the change in specific enthalpy of pure n-butane from
375°C to 105°C?
d) What is the change in specific enthalpy of the mixture...
A 46.0%/54.0% by volume propane/n-butane mixture is cooled from
255°C to 193°C. FInd the change in ethalpy of this mixture by
following the steps below. Assume ideal behavior. a) What is the
average molar mass of the mixture? b) What is the change in
specific enthalpy of pure propane from 255°C to 193°C? c) What is
the change in specific enthalpy of pure n-butane from 255°C to
193°C? d) What is the change in specific enthalpy of the mixture
from...

n-butane molecule is 0.55 nm2 at 85 °C,
estimate the surface area of the catalyst (in m2/g)
assuming Langmuir adsorption isotherm.
In the following problem:
1. Determine the value of the margin of error ( E ) 2. Construct
the confidence interval. 3. Write a statement that correctly
interprets the confidence interval.
From a Prince Market Research poll in which randomly chosen people
were asked if they felt that U.S. nuclear weapons made them feel
safer the following data was gathered. Construct a 95% confidence
interval for the proportion of all people living in the United
States who felt nuclear weapons...
