At a given set of conditions, 246.2 kj is given off when 1 mol of h2o(g) forms from its elements. under the same conditions, 284.6 kj is given off when 1 mol of h2o(l) forms from its elements. find δh for the vaporization of water at these conditions.

The ΔH for the vaporization of water at these conditions is 38.4 kJ/mol.

Explanation:

Given:

..[1]

..[2]

To find: ΔH for the vaporization of water at these conditions:

...[3]

Solution:

[1] - [2] = [3] (using Hess's law)

The ΔH for the vaporization of water at these conditions is 38.4 kJ/mol.

h let me think

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck
