Answer:
200/3 M which is approximately equal to 66.6667 M
Explanation:
Molarity is defined as the number of moles of solute per liter of solution.
It can be calculated as follows:
We are given that:
number of moles of solute = 8 moles
volume of solution = 120 ml = 0.12 liters
Substitute with the givens in the above equation to get the molarity as follows:
molarity =

Answer : The value of is 28.97 kJ/mol
Explanation :
To calculate of the reaction, we use clausius claypron equation, which is:
where,
= vapor pressure at temperature
= 462.7 mmHg
= vapor pressure at temperature
= 140.5 mmHg
= Enthalpy of vaporization = ?
R = Gas constant = 8.314 J/mol K
= initial temperature =
= final temperature =
Putting values in above equation, we get:
Therefore, the value of is 28.97 kJ/mol
