Answer:
5.51mol/L
Explanation:
Number of moles = 1.35moles
Volume of the solution = 245mL = 245*10^-3L = 0.245L
Molarity of a solution is the defined as the number of moles of a solute dissolved in 1L of the solution.
1.35 moles = 0.245L
X moles = 1L
X = (1.35 * 1) / 0.245
X = 5.51mol/L
The molarity of the solution is 5.51mol/L
Answer:
Explanation:
Hello,
In this case, considering that the formed liquid is solution is ideal, we can relate the vapor pressure and molar fraction of water with the total vapor pressure of the solution by using the Dalton's equilibrium-based law:
In such a way, we compute the molar fraction of water by computing its moles as well as diglyme:
Thus, the mole fraction of water:
Thereby, the vapor pressure of the solution:

Refrigerants are chemical mixtures composed of several substances. During the HVAC cycle, <span>refrigerants can usually exist in several states.
These substances have very dangerous and destructive effects on the environment.
Based on this, if two or mire </span><span>refrigerants are mixed together, the mixture must be recovered into a separate tank and sent to the specialized facility to destroy it.
The destruction of the mixture should only be done by experts in specialized facilities.
Hope this helps :)</span>
Lunch of a patient has 3 oz skinless chicken, 3 oz of broccoli, 1 medium apple, and 1 cup of nonfat milk
Energy content of 3 oz skinless chicken is = 110 kcal
Energy content of 3 oz broccoli = 30 kcal
Energy content of 1 medium apple = 60 kcal
Energy content of 1 cup non-fat milk = 90 kcal
So the kilocalories of energy patient obtained from lunch
= 110 kcal+ 30 kcal + 60 kcal + 90 kcal = 290 kcal
