At sea level water usually boils at 100. °C and 760. mmHg pressure. On Mt Whitney, the pressure is about 560. mmHg. At what temp
erature, in degress Celsius, does water boil on Mt Whitney?
1 answer:
Answer:
91.7°C
Explanation:
We suppose you have a formula to work from. However, that is not supplied with this problem statement, so we looked one up.
The formula in the attachment is supposed to have good accuracy in the temperature range of interest. It gives vapor pressure of water in kPa, not mmHg, so we needed the conversion for that, too.
560 mmHg corresponds to about 74.66 kPa. The attached "Buck equation" formula is used to find the corresponding temperature. The exponential equation could be solved algebraically using logarithms and the quadratic formula, but we choose to find the solution graphically.
Water boils at about 91.7 °C on Mt. Whitney.

Answer: 3) 39.96 amu
Explanation:
Mass of isotope Ar- 36 = 35.97 amu
% abundance of isotope Ar- 36= 0.337% =
Mass of isotope Ar- 38 = 37.96 amu
% abundance of isotope 2 = 0.063 % =
Mass of isotope Ar- 40 = 39.96 amu
% abundance of isotope 2 = 99.600 % =

Therefore, the average atomic mass of argon is 39.96 amu
Answer:
is the value of the equilibrium constant at this temperature.
Explanation:
Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of products to the partial pressures of reactants each raised to the power equal to their stoichiometric ratios. It is expressed as
Partial pressures at equilibrium:
The equilibrium constant in terms of pressures is given as:
is the value of the equilibrium constant at this temperature.
