The molar heat of the vaporization of ammonia i 23. 3 kJ/mol. What i the molar
dimaraw [331]

The molar heat of vaporization of ammonia is 23.3 kJ/mol. The molar heat of condensation of ammonia is - 23.3 kJ/mol.

The molar heat of condensation is the opposite of the molar heat of vaporization. The molar heat of vaporization of ammonia is given :

ΔH evaporation = - ΔH condensation

Therefore the molar heat of  condensation of ammonia is given by:

ΔH condensation = - 23.3 kJ / mol

That's right. The molar heat  of vaporization of ammonia is 23.3 kJ/mol. The molar heat of condesation of ammonia is - 23.3 kJ/mol.

What is the molarity of .0000000342 grams of adenosine 3'5' cyclic monophosphate (CAMP) in one lite
Doss [256]

<u>Answer:</u> The molarity of solution is 1.0388\times 10^{-10}M

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (in L)}}

We are given:

Mass of solute (CAMP) = 0.0000000342 g

Molar mass of CAMP = 329.21 g/mol

Volume of solution = 1 L

Putting values in above equation, we get:

\text{Molarity of solution}=\frac{0.000,000,0342g}{329.21g/mol\times 1L}\\\\\text{Molarity of solution}=1.0388\times 10^{-10}M

Hence, the molarity of solution is 1.0388\times 10^{-10}M
