An you make the methodology in paragraph?

Equipments and Glassware:

• PARR 1455 Solution Calorimeter, 100 ml graduated cylinder

Reagents:

• Distilled water, Ammonium chloride

Procedure:

1.       Prepare the molar enthalpy vs. concentration profile of ammonium chloride-water solution by preparing different amounts (mass) of ammonium chloride to be dissolved in the same volume of water.

2.       Start with at least 0.1 g sample of sodium chloride (make ten (10) different mass with at least 0.1 g increment) and place it in the Teflon dish.

3.       Measure 100 mL of distilled water and place it in the Dewar flask.

4.       Set-up the Parr 1455 Solution Calorimeter.

5.       Press F1 to start the initiation stage.

6.       Note the sample ID and press ENTER.

7.       Input the exact weight of the sample and press ENTER.

8.       Wait for the first beep and fire the push rod and press ENTER.

9.       Wait for the second beep and press DONE.

10.   Browse the result using the arrow up (↑) and arrow down (↓) keys.

11.   Repeat procedures for the next samples.
