All i need is hel pwith question number 4 according to the data given. Thank you

are data to determine the change in pressure, AP, during the reaction. In addition, determine the mean temperature of the water bath during the reaction. Record these values in your data table. From the Experiment menu, choose Store Latest Run to save your data. Rinse, clean, and dry the flask for a second trial. Obtain a new piece of magnesium ribbon 12. 13. and place it in the flask. Repeat the necessary steps to conduct the second trial DATA TABLE Trial 1 Trial 2 Average Mass of Mg (g) Volume of flask (mL) Maximum pressure (kPa) 36 L Initial pressure (kPa) 02.0%o sake- Pressure change, AP (kPa) Temperature (K) DATA ANALYSIS .

Explanation / Answer

Ans. Given,    

Calculated molar volume at STP = 22.41 L = 22.4 L       ; (3 significant figures)

Ideal (theoretical) molar volume at STP = 22.4 L            ; (3 significant figures)

# Both the calculated and theoretical molar volume at STP are exactly the same (100.0 % agreement). So, the experiment has been carried out correctly, there occurred no experimental errors during the experiment.
