Answer:
Approximately (note that
.)
Explanation:
The molarity of a solution gives the number of moles of solute in each unit volume of the solution. In this solution in water,
Let be the number of moles of the solute in the whole solution. Let
represent the volume of that solution. The formula for the molarity
of that solution is:
.
In this question, the volume of the solution is known to be . That's
in standard units. What needs to be found is
, the number of moles of
in that solution.
The molar mass (formula mass) of a compound gives the mass of each mole of units of this compound. For example, the molar mass of is
means that the mass of one mole of
.
For this question,
.
Calculate the molarity of this solution:
.
Note that (one mole per liter solution) is the same as
.
The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.
The heat of vaporization has been the amount of heat required to vaporize 1 gram of liquid.
The heat required for the vaporization has been given as:
The heat of vaporization of water has been given as,
The mass of water sample has been,
Substituting the values for the heat energy absorbed, <em>Q:</em>
<em />
<em />
The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.
